Case study: The Battle for Jezeří Chateau
For Jezeří Chateau, perched dramatically on the foothills of the Ore Mountains in North-West Bohemia, its struggle for survival has been an enduring one over the centuries and reached its most critical moments in the latter half of the 20th century long after pan-European wars were consigned to history. From its role as a troop base in the Hussite Wars, the various radical reconstructions it underwent, its numerous changes of ownership, and its use and misuse by German troops during the Second World War, Jezeří Chateau still faced almost inevitable ruin through deliberate neglect from the 1950s onward when the communist regime became transfixed by extracting as much of the surrounding coal deposits as possible, even at the expense of demolishing the chateau itself. Even now, after a successful fight to preserve the building, the threat of demise looms over the chateau once again as part of the equation to lifting the territorial mining limits imposed in the early 1990s.
The early history of the chateau
Even the landscape under the Ore Mountains has been through many radical changes, including the destruction of the villages Ervěnice, Nové Sedlo, Komořany, Třebušice, Dřínov, Albrechtice and Dolní Jiřetín, though one can still admire the genius of the builders from times gone by who couldn’t have chosen a more natural site for the chateau. It isn’t, however, just the calibre of this first class architectural landmark that impresses us. The chateau has also played a dominant role in the history of the region.
Today’s baroque structure covers a renaissance chateau, which in turn covers a gothic chateau. We could go even deeper into its history and look at the original Slavic settlements of the entire region. This site was chosen even earlier for their settlement by the Celts, who had their main settlement and holy sites on the slopes of the Ore Mountain foothills. Today, Jezeří Chateau is a monument of the first category, exceptional not only for its extraordinary and architectural value, but also its unsettled fate, it’s unusually beautiful location and its importance for the present and future development and shaping of life in the sub-Ore Mountain landscape.
The Gothic Chateau
There used to be a medieval chateau on the site of the present day chateau, but its founding date is unknown. The first written record of it dates from 1363-65 and states that the chateau was owned by the masters of Rvenice. Even then we encounter the names “de Lacu” (of the Lake) as well as “of Aysemberg”, also reflected in the old German name Eisenberg, logically connected to ore mining in this part of the Ore Mountains.
Bušek of Eisenberg sold the chateau in 1406 to Petr of Perč; the next owner of the property was Albrecht Sn. of Kolowrat. After his death, Jezeří was passed on to Jan Smolík of Slavice, a Catholic supporter who managed to hold the estate throughout the Hussite Wars. He left the chateau to his son Zikmund, who was known for his dislike of Saxons. Owing to this fact, there were frequent skirmishes between Jezeří and the Saxon troops at the nearby chateau of Hněvín.
The next owner of the chateau, the knight Kunz of Kaufunk (1450), also backed the interests of the kingdom of Bohemia, although his family came from Saxony. The reason for his attitude, however, was animosity between the Kaufunk family and the Prince Elector Friedrich of Saxony. The conflict escalated in 1455 when Kunz abducted the elector’s sons from the chateau of Altenburg to force Friedrich to give back the Fictum estates he had confiscated from him. Jezeří was supposed to be the place where prince Arnošt was held, but this intention never came to be. Kunz of Kaufunk and his men were caught on the Saxon side and Kunz was executed at Freiberg in 1455. Worried about the fate of Kunz’s sons, Kunz and Heinrich, the regional governor Jiří of Poděbrady took possession of the chateau and made use of the presence of his troops at Jezeří to capture the town of Most.
In 1459, the Smolík family returned to Jezeří and the last of them, Zikmund, bequeathed the chateau to his brother-in-law, Mikuláš Hochhauser of Hochhaus, in 1513. It was probably then that the chateau was rebuilt as a renaissance chateau.
The Renaissance Chateau
The conversion of the medieval chateau into a renaissance chateau was finished in 1549. There is an ornamental stone wedge over the main gate that commemorates this event. The wedge bears the coat of arms of the Hochhauser family, the year 1549 and an inscription stating “O people, remember where the master is and his family.”
When Mikuláš died, his son Petr took over the chateau, and from him it was passed on to his sons Václav Jr. and Mikuláš. The latter later bought the part belonging to his brother, but unfortunately died fighting the Turks at the Battle of Jager in 1569. The estate went back to his brother Václav, who sold it to his cousin Jiří Hochhauser of Hochhaus in Albrechtice. Jiří’s son Jan Mikuláš (who owned the chateau from 1605) was punished for his participation in the Bohemian Revolt of 1618 by having his fortune confiscated in favour of the emperor Ferdinand II.
The emperor gave Jezeří together with other estates to prince Karl of Liechtenstein by an edict of 15 March 1622. The new owner sold it almost exactly a year later (24 March 1623) to Vilém Popel Jr. of Lobkowicz in Bílina for 80,847 Meissen three-scores. Vilém, however, only paid for two thirds of the estate – 67 956 three-scores. The other third remained in Hochhauser possession and Vilém was supposed to pay the rest of the price to the heirs of Jan Mikuláš. Apparently, he failed to do so, because in 1631, during the Saxon invasion, Jiří and Bernard Hochhauser, who had lived in exile until that point, returned to Jezeří, pilaged it completely and “took whatever could be taken”. The financial disputes between Lobkowicz and Hochhausers were settled completely only in 1638.
To the great advantage of historians, a description of the renaissance chateau has been preserved. It had been made for the occasion of selling the chateau. The catalogue mentions the foreroom, the masters’ room, the kitchen, the buttery and pantry, three rooms for maids, an upper closet, the ladies’ room and closet, the hind closet, the upper chamber, the hall, the schoolroom, the second hall, a lower vaulted chamber, a masters’ closet and chamber, and the clock tower. There was an orchard around the chateau that included fruit and walnut trees, among other types. There were also three derelict vineyards, and below the chateau was a brewery and a Meierhof (a farm belonging to the local gentry). The estate also consisted of five villages and three other Meierhofs.
An account from October 1621 describes the chateau of Jezeří as “heavily damaged by soldiers”, not one window was intact and the doors and floorboards were torn out. Minor reconstructions, however, began at the chateau as soon as 1627; in 1638 the “brick roofs” were being repaired.
Unfortunately, on 18 February 1646 the chateau caught fire and burned to the ground, with the exception of a small tall building and the stables. A year later, Vilém Popel died and the estate went to his son František Vilém, the founder of the Nové Sedlo-Jezeří branch of the family. There were, however, no significant alterations to the chateau carried out during his lifetime.
The Baroque Alterations
The chateau came to be significantly altered during the lifetime of František Vilém’s son – Ferdinand Vilém of Lobkowicz, who resided at Nové Sedlo until the work was finished and only moved to Jezeří in 1697. The year 1696 over the main gate must therefore mark the end of the chateau’s alteration. We can correctly assume that at this point Jezeří was a magnificent place in full alignment with contemporary ideas of a family residence. Unfortunately, the name of the project’s architect remains unknown; we don’t even know the reason why the greater part of the Lobkowicz archives were not preserved.
The main longitudinal building with its four perpendicularly adjacent wings formed an H-shaped ground plan, with the hall buttress coming out of the southern side. In front of the main frontispiece with a shallow central buttress ending in a prismatic tower, there was the court of honour. At each side of the main portal there are atlantes by Jan Adam Dietz from the mid-1800s.
As Ferdinand Vilém had no male heirs, he bequeathed his estate to his brother Oldřích Felix, who took over after his tragic death. On 25 September 1713 there was another fire at the chateau. Oldřich Felix, who had gone hunting that day, returned to see the building ablaze – the fire had spread so much by then that it could not be extinguished. Thanks to the committee sent by the hetman of Žatec to ascertain the damage, we now know how some of the rooms at Jezeří had looked before the fire and we can tell that the chateau already had the outer shape it has today. Unlike its renaissance predecessor, which had a tiled roof, this one only had shingles. On the middle floor there was a “new, spacious and beautiful ballroom with an oval, stucco-decorated vault, with huge columns and mascarons which took a group of ten masons, two stuccoworkers and six carpenters a whole summer to complete”. The room had nine windows and the damage inflicted by the fire was worth at least 4500 guldens. The adjacent room, by the “new dining hall”, with stuccoed ceiling and a beautiful floor was also completely destroyed (damage worth 388 guldens); another of the long list of destroyed rooms had been painted „al fresco“ (damage amounted to 350 guldens), and the alcove had a stuccoed ceiling and a valuable floor, too (350 guldens). In two adjacent rooms the fire also ruined frescoes, stuccoes and floors and its heat melted two beautiful tile stoves. In the great dining hall next to the chapel, decorated with stuccoes, a big green tiled stove was destroyed as well as a double door made of oak (damage worth 400 guldens), the fire also devoured the red room next to the dining hall, and the room next to that, a gilded study with stuccoes and frescoes on the ceiling, and another alcove (1400 guldens in total). The main helical staircase was destroyed as well as the old and the new towers with their little chambers, the “forest room” and the painted chamber, the kitchen with its foreroom, Count Lobkowicz’s painted rooms, four offices, a closet as well as a great hall above the dining room with a beautiful ceiling and floor, four capuccin rooms and another office. The fire did not spare the middle tower with a clock and two bells either, nor two dormers. A separate building below the chateau with six rooms, three closets and a laundrette was burned to the ground. The orangery, the lathe workshop, the new sawmill and other well-documented rooms and space also turned to ashes. The total damage soared to 30,398 guldens, 19 kreutzers and 3 denari.
Oldřích Felix decided to use his “modest means” to renovate the chateau the same year, and probably barely managed to do so just before his tragic death in 1722. He was also the last member of the Nové Sedlo-Jezeří branch of the Lobkowicz family, therefore the will of 4 September 1722 leaves the estate to Karel Adam - once he attained his majority – and until then it was to be managed by his father, Jiří Kristián of Lobkowicz. Karel Adam then formally sold Jezeří to Ferdinand Filip Josef, Prince of Lobkowicz in Roudnice, in 1752, thus passing the chateau, as was expected, to the Roudnice-Bílina line of the family.
Early to mid-20th century history
The turn of the century
In the time of Ferdinand Filip (from 1752), the chateau was in good condition, and therefore it was enough to simply carry out regular maintenance. After Ferdinand Filip’s death, the estate went to Josef František Maxmilián, whom we connect with a flourishing art life at the chateau (Musical Past), as well as with major alteration works. The purpose of those was to adapt the chateau to meet requirements for what was then deemed the adequate comforts of a nobleman’s lifestyle. Minor reconstruction works were carried out as soon as 1797, but the main phase of the alterations began in 1802. The structure and use of individual rooms has more or less been preserved to this day. The extensive adaptation of “piano nobile” was carried out in the northern as well as the southern part of the chateau (the theatre hall and the new chapel).
After František Maxmilián’s death, Ferdinand Josef of Lobkowicz became the 8th Prince of Roudnice. In 1821, negotiations for including Jezeří in the family inheritance began. The negotiations were successfully closed in 1835 when this permit was filed in the Land Register. In 1868 Prince Mořic of Lobkowicz became the manager of the family inheritance, and after him it became Ferdinand Zdeněk, who assigned the management to his second-born son in 1920. JUDr. Maxmilián Ervín of Lobkowicz studied law and then became an important diplomat in the services of Czechoslovakia. This was the reason he went into exile in the UK in 1938 and became equally important in the Czech anti-fascist movement there.
Jezeří during the Second World War
After Munich 1938, the Lobkowicz domains were broken up – those that found themselves in occupied territory were administratively assigned to the “firm hand” of a directorship in Bilina. Immediately following the first days of the occupation, the chateau was occupied by the staff of “SS-Leibstandarte Adolf Hitler” headed by Obersturmbannführer Sepp Dittrich. A large part of the moveable chattels were taken prior to the Sudeten conquest to Roudnice nad Labem, although following the take-over the Lobkowicz property had to be returned to Jezeří; it was later transferred to Bílina.
Hitler’s personal banner departed Jezeří on 19 October 1938, when the chateau was occupied by a garrison designated to keep watch over prisoners who were accommodated close to the forestry management offices at Jezeří. These prisoners were Poles, Russians and Frenchmen, as well as German soldiers on criminal charges. In March 1943, the chateau was used for prison purposes. A special camp was established there for prominent persons “Sonderlager für prominente Persönlichkeiten” – mainly highly placed French officers. A labour commando of 96 men from the Flossenbürg concentration camp also came to the chateau. The whole chateau was painted a camouflage green. Guardhouses were constructed around the building connected by electric fences and patrolled by guard dogs. The wider surroundings were closed to the population. In the chateau itself, an average of around 100 people were accommodated. From 1943, about 238 men went through this camp. Among the prominent personalities interned at Jezeří were Pierre de Gaulle – the brother of the future French president Charles de Gaulle, the son of the former French premier Michael Clémenceau, Dr. Menetrel – Marshal Pétain’s personal physician, Prince Michael Montenegra, and others.
The Communist Putsch and the start of the chateau's downfall
After the end of the Second World War, the chateau and its lands were over time returned to the ownership of the Lobkowicz family; it is said that guests at that time included the Czechoslovak Foreign Minister Jan Masaryk. The Czechoslovak ambassador to Great Britain, JUDr. Maxmilián Lobkowicz, remained faithful to democracy after the Communist putsch of February 1948 and decided to remain in exile.
Soon after the February “victory” – on 20 April 1948 – the Provincial National Committee introduced national administration at Jezeří. On 21 August 1949, the chateau was taken over by the National Culture Commission. The state of the chateau was declared to be bad, especially in relation to the roof, the plaster and castellated decoration of the bannisters on the rear terrace, while the floors were seen to be in good condition. The chateau was first rented out to the Ministry of Technology, but on 22 September 1950 the government decided to make it available to the Ministry of National Defence; it was specifically allocated to the management of the Chomutov garrison.
The “takeover” of the chateau took place on 28 August without notifying the National Culture Commission and the State Monument Administration in a way that completely contradicted the principles of these institutions. The 100-member garrison simply occupied the chateau, threw the remaining inventory into the chapel, and whitewashed the whole chateau in their own style both in reality and figuratively. The Czechoslovak People’s Army tried to adapt the chateau grounds completely to its own needs. The interiors were destroyed, many rooms in the chateau were intentionally modified and the remaining furniture stolen or destroyed.
In 1955, the chateau was taken over by the Ministry of Interior. In line with a decision dated 9 January 1958, administration was delegated to the Ministry of Education and Culture, Monument Care Department. On 29 August 1958, the chateau was transferred to the State Monument Administration, and then in 1959 it was transferred to the Regional National Committee in Ústí nad Labem. At that time there was no security provided at Jezeří and the chateau was left exposed to vandals from 1960. From 1961 to 1972, the chateau was administered by the District National Committee in Most when the first project for reconstructing the building was drawn up. Its author was the Institute for Landscape Creation and Protection of the Czechoslovak Academy of Sciences, which had responsibility for supporting Jezeří in its research programme. A further anticipated use of the chateau consisted in the intention to build an extensive recreational area of supra-regional importance, but everything remained an idea only, just like the declared intention to have exhibitions of famous musical traditions.
From 1964, artistic-historic and construction research was undertaken under the leadership of Václav Mencl. The subsequent reconstruction was methodologically contributed to by the Regional Centre of State Monument Care and Nature Protection in Ústí nad Labem, although its collaboration with the Usti-based District Construction Enterprise only led to the further devastation of the building. At the same time as the demolition of the unmaintained chaplain’s dwelling and kitchen annexes, the north-east wing of the chateau and the underlined buttress were seriously damaged, known these days as the oriel. This desperate situation was allowed to continue for the whole of the following period without any security, and it is testimony to its solid and honest construction that no other parts of the building fell apart. In 1967, the then administrator permitted further gross interference by the District Construction Enterprise from Ústí nad Labem by ripping up around 150 m² of parquet flooring and its subsequent use at the chateau in Ploskovice. The District National Committee in Most reconstructed the gatehouse as a temporary dwelling for a guard, and in 1972 the chateau was transferred to the administration of the Regional Centre of State Monument Care and Nature Protection in Ústí nad Labem. Further reconstruction was therefore postponed indefinitely. The chateau administration at that time prohibited even normal maintenance being carried out and justified neglecting the state of the chateau on the grounds of the ambiguous situation regarding the mining activities of the North Bohemian Lignite Mines.
The period of greatest threat
Coal undermines the existence of the chateau
In the years 1973-76, engineering-geological mapping was undertaken in the foregrounds of the Czechoslovak Army opencast mine, from whose conclusions stemmed a desperate need for more detailed research of the coal basin limits in 1980s. This mainly confirmed the fears that the extent of the crystalline massif of the Ore Mountains could significantly influence coal mining activities and vice-versa. It was found that it was necessary to urgently verify the state of the crystalline massif, its disrupted tectonic plates, efflorescent processes and landslide activity in the very places where the coal basin limits abutted the Jezeří chateau grounds. The responsibility for the research was given to Construction Geology Prague under the research management of RNDr. Jan Marek.
In 1975, Dr Marek informed the Regional Office of State Cultural Heritage and Nature Conservation of the risk to the Jezeří Chateau heritage building and the surrounding mountainsides. He set up a permanent field office in an abandoned old tower of the chateau with the Regional Office’s approval.
The critical site became popular after he submitted his final report on the engineering geological mapping and especially after his articles were published. Czechoslovak Television asked him to on their economics show “Is It Worth It?” from the chateau courtyard. Jezeří started to host journalists, political officials, leading scientists, entire busloads from the Regional Mining Authority in Most, Báňské projekty in Teplice, the Regional Office of State Cultural Heritage and Nature Conservation in Ústí nad Labem, the Central Geological Institute, various institutes of the Czechoslovak Academy of Sciences, and universities in Prague, Brno, Ostrava, Bratislava and Košice. Josef Velek – the only journalist with an openly pro-environmental focus – arrived. Dr Marel spent several evenings debating with this young author of such well-known books as “Jak jsem bránil přírodu” (“How I Protected Nature”), “Příběhy pro dvě nohy” (“Stories for Two Legs”) and others that the communists in control didn’t like much. He began to write a new book about the Jezeří problem, but never completed it: he died diving in the Red Sea soon afterwards. Wagging tongues said somebody pushed him.
The growing popularity of the Jezeří area was in sharp contrast to the frightening state of neglect of the chateau itself. The expansive building had been abandoned in 1954, it had been stripped of all its furnishings (burgled) and managed in a hands-off way by the Regional Office of State Cultural Heritage and Nature Conservation by means of a single custodian. Outside the scope of interest of district or region-level political authorities, it was rapidly decaying. To make the responsible political and administrative authorities and, more importantly, mining institutions aware of the real value of the building, Dr Marek compiled an overview of its historic and structural development, assessing its importance, and published it in the North Bohemian Mines professional journal “Hnědé uhlí” (“Brown Coal”).
A new geological survey is commissioned
The practical result was that, almost simultaneously, both the State Cultural Heritage Conservation and the general management of North Bohemian Mines commissioned Stavební geologie to perform a new, detailed, purpose-driven engineering geological survey of the Jezeří area. It was obvious beforehand that the survey was primarily meant to either confirm or refute his conclusions and interpretations made as part of the previous geological mapping. It was also evident that it would not succeed without unconventional and costly mining engineering methods, tunnels, shafts and deep core holes. It was not clear beforehand where to put them, what sizes to make them, who would design them, who would make them and how, and who would pay for them. A professional project design had to be made for each separate mining facility. In order to clarify those issues, Dr Marek spent the whole of 1977 making a detailed survey of the cellars and other underground spaces of the Jezeří Chateau grounds, and commissioned geophysical measurements in several points along the chateau buildings and the surrounding slopes where he had predicted the existence of tectonic fault zones. Only after that did he design subsequent, technically demanding works. He had his entire design reviewed by the most distinguished professionals, his old professors Quido Záruba and Vojtěch Mencl, the founders of the scientific discipline of engineering geology. They both came to Jezeří several times despite their advanced age of around 80 years.
Problems with finding a company to accept the commission
A team of designers at Báňské projekty Teplice – the last ones who still knew how to design underground mining works in the North Bohemian Basin – were charged with drawing up the technical designs for the mining works. At the foot of the hill under the chateau, Dr Marek proposed a vertical shaft and two horizontal galleries under one another, dug towards the mountains; the bottom gallery was to be dug from the bottom of the shaft. Their purpose was to detect and cross the predicted tectonic fault zones. However, the mining engineers gave up on the job after a year spent designing it. There was no-one at hand who would be willing to carry out the designed work.
The Central Committee of the Communist Party decided that the costs of the designed works were to be paid by the North Bohemian Mines (Doly V.I. Lenina [V.I. Lenin Mines], later renamed Mostecká uhelná společnost [Most Coal Company]). So Dr Marek borrowed Stavební geologie director’s managerial Tatra 613 with a driver, put two mine development officers with signed and stamped authority in their pockets in the car, and started to tour Czechoslovakia. They tried to enter into contracts for the work at Jezeří with well-known companies that did mining work. They failed in Rýmařov and in Zlaté Hory near Jeseník and in Žilina and in Spišská Nová Ves.
In the meantime, Jáchymov-based Výstavba dolů uranového průmyslu (VDUP – a uranium mining company) began digging a hydraulic tunnel in the mountainside above Jezeří to divert the Šramnický brook, and then another tunnel at Albrechtice to divert the Černický brook to the reservoir at Loupnice. Dr Marek and his team monitored the digging of both tunnels for over a year. They closely documented of the geological phenomena detected in depth within the crystalline complex to have enough background information for comparison for the planned survey under Jezeří. However, they were only able to do that at night, when the digging underground was halted for the day. To make even more work for themselves, they also took up documenting the new three-kilometre-long drainage tunnel in Jáchymov.
Thanks to co-operation with VDUP Jáchymov, they succeeded in convincing the company’s diggers to perform at least part of the planned mining work under Jezeří after the digging was completed. Most importantly, they managed to do the principal work: the horizontal gallery dug from the mountain base into the crystalline complex right under the chateau, 430 m long. They were documenting the gallery throughout the digging process; again, mostly at night. Deep core holes were bored in front of the gallery portal; an underground hole was bored inside the gallery, and an inclined core hole was bored under the chateau foundations. They documented all the rock formations around the chateau. They measured all the fissures, analysed the geodynamic phenomena and other facts. They found and documented the remains of medieval chambers for iron ore extraction and processing in old “salamander furnaces” discovered around the chateau. Dr Marek published the findings in the professional journal “Rudy” (“Ores”), which later resulted in their inclusion among protected national technical heritage sites.
Confirmation and praise for geological findings
The research around Jezeří took more than 4 years and was completed in 1981. It fully confirmed the findings and conclusions of the previous engineering geological mapping, which the North Bohemian Mines management would not accept in 1976. It confirmed the existence of massive tectonic fault zones at the mountain base and inside the massif, various anomalies in the positioning of the basin sediments along the seam edge and the groundwater conditions, and most importantly, it confirmed the unstable position of the promontory on which the chateau rests.
Dr Marek was writing the final report on the Jezeří survey in bed at the Institute for Clinical and Experimental Medicine (IKEM) in Prague, where he had been taken after he collapsed as a result of extreme physical strain, long-term mental exertion, dangerous work in the underground and staying in the unheated tower at Jezeří.
When he was put more or less back together at IKEM, he defended his set of findings and generalised experience as his Candidate of Sciences dissertation thesis at the Charles University Faculty of Science. The thesis was reviewed by three top experts at three universities whose expertise it involved: the geotechnician Prof. Mencl of Brno Technical University, engineering geologist and hydrogeologist Prof. Homola of Ostrava Mining University, and geomorphologist Prof. Král of the Charles University Faculty of Science. They assessed it as the best in years and the most momentous in the Czechoslovak Federation, with a direct impact on the entire country’s economic situation. It seemed that the battle was over and there could be some resting on laurels at last. The reality soon proved otherwise, though.
Additional mathematical modelling reinforces potential danger of continued mining
The results of Dr Marek’s research were to be confirmed by a mathematical calculation of the stability of the slope. This was an extremely tall slope, however, its integrity had been disrupted by tectonic zones, and its base was meant to be lightened through coal mining. There was no one at hand who wanted to take on that task without sufficient previous experience and examples from foreign literature. Eventually, the calculation was taken up by the country’s most experienced experts, geotechnician Vojtěch Mencl and mathematician Ladislav Mejzlík, both emeritus professors at Brno Technical University. They used the finite element method, novel in the Czech Republic at that time, using computer equipment. In addition, a physical model was constructed at the BTU Construction Faculty Geotechnics Department made of equivalent materials (Jezeří Chateau being represented by two sugar cubes).
While the professors were doing their calculations, the lecturers and instructors in white coats were working with the physical model located inside transparent plexiglass walls. They used a toy spade to rake away fine sand, which stood for the basin sediments, imitating the mining activity in the opencast mine. The condition of the adjacent crystalline complex was monitored by means of a network of surveyed points; movement was expected, and Dr Marek was cautiously watching along with renowned experts from the Academy of Sciences. After all the sediments were removed, nothing shifted until late at night; the sugar cubes remained in place. The next morning, they found the massif had collapsed complete with the sugar cubes.
The mathematical calculation confirmed that removing the top two-thirds of the sediments at the base of the mountainside might not cause a stability collapse of the entire slope, but the bedrock directly under the chateau would suffer deformities of up to 10 cm. A total collapse in stability would occur if the basin fill extraction continued. (The coal seam is located in the bottom segment of the sedimentary strata series.)
Jezeří becomes national research site to test further data on mathematical and physical modelling
Moreover, the course of both the mathematical and physical modelling showed a deficit in some input data, the importance of which only became clear during the modelling, such as the role of discontinuous groundwater horizons, the size and orientation of the natural tension inside the crystalline complex at the mountainside base, the role of slow secular movements of the massif due to internal geological forces, etc. That was why the Jezeří area immediately became a test site in which various professional institutions and teams of specialists tried to test various empirical approaches to modelling, conduct parametric studies and regression analyses. Eventually, Stavební geologie Praha became the manager of an extensive national research task “Studying stability problems of opening opencast coal mines at the base of the Ore Mountains”. As part of this, Dr Marek dealt with the issue of “Studying the tectonic loosening of the crystalline complex”. Using inclined and horizontal core holes in the mountainsides around Jezeří, he examined the presence of tectonic faults and zones, verified their tectonic effects in the ground surface, and tested possible applications of various geotechnical equipment for monitoring changes in the tension and movement inside the massif. The research was completed in 1986.
After Dr Marek submitted the results of the detailed survey at Jezeří, the mine management commissioned detailed engineering-geological surveys of similarly critical sites below Jezerka, at Černice and Horní Jiřetín, again using elaborate mining work. The mining work was taken up by the tried and tested VDUP Jáchymov, which was then able to dig vertical shafts in addition to horizontal galleries. At the same time, comprehensive surveying started on the adjacent site in the forefield of the disused Obránců míru opencast mine, between Jezeří and Janov, covering another approx. 20 km2. Its chief focus was on the stability of the mountainsides and the end slopes of the planned opencast mine. Dr Marek continued the detailed engineering-geological mapping of that section and kept track of all the other survey and research works.
Detailed survey results championed by incipient environmental movement
Immediately after the conclusion of his detailed survey at Jezeří in 1981, Dr Marek held a seminar for the staff of the Regional Office of State Cultural Heritage and Nature Conservation in Ústí nad Labem about its results and predictions for the future progress of the coal mines. The seminar was also attended by the heads of the then newly formed youth conservationist movement “Brontosaurus” from Most and Litvínov, Miroslav Brožík and Petr Pakosta. Dr Marek invited them to make use of the assistance of young environmental activists to help in saving and rehabilitating the devastated chateau, its gardens and the former parks around it. The Brontosaurs pulled their weight effectively with the consent of the Regional Conservation Office, but to the displeasure of the District Committee of the Communist Party in Most. The latter regarded their action as a violation of Party guidelines, which were unequivocally in favour of the coal mining. They saw no gratitude either when they cleared out the devastated historical Franciscan hospital in Most, scheduled for demolition, and prepared it for renovation.
The youth group ran the “Quite Small Theatre” in Litvínov, where they invited well-known people in environment-related professions for discussions with locals. In 1982, they invited Dr Marek to lecture on “Shall we prop up the Ore Mountains?” The feedback was considerable. The public of Litvínov, Most and the surrounding villages revived their interest in conserving not only Jezeří but also the surrounding landscape and the remaining settlements. Discussion evenings followed, involving presentations by Dr. Skřivánek of the State Conservation Office headquarters, Dr. Vaněk and Ing. Stoklasa, both renowned experts of the Academy of Sciences Institute of Landscape Ecology, and others. They all endorsed the continued existence of the chateau.
Authorities continue to support mining, but in modified form
With minor variations, the detailed surveys below Jezerka, at Černice and Horní Jiřetín produced findings similar to those from the Jezeří survey. The mountainsides and their bases were modified by tectonic fault zones up to several dozen metres thick. Within them, the crystalline rocks were crushed or even disintegrated into a sandy-clay earth. The basin strata series at the edge of the basin were also disrupted by various fault and non-fault deformities.
Now the problem was how the mine planners and operators would cope with that because they still insisted on their original plan to fully deplete the seam up to the edge using the large-scale opencast method, albeit at the cost of disproportionate expenses and special precautions, the technical and energy intensity of which would clearly outstrip any profit from the coal mined.
Jezeří threatened with demolition by new mining design
Design ideas verging on fantasies were developed, including stabilization of the Ore Mountain massif using a series of pretensioned anchors up to 80 m long, bored from slope sections cut into terraces. Another was to remove the entire exposed section of the crystalline complex so that the end slope of the opencast coal mine would face mountain slopes dressed at a stable incline of approx. 35°. Obviously, that would have required the complete removal of the forest, the groundcover, the protruding rock formations, and naturally, Jezeří Chateau. The latter version was even elaborated into an implementation design, undersigned by Ing. Kubricht, former chief architect of Most and a designer at Báňské projekty at that time. To that end, the mine management, the Brown Coal Research Institute in Most and Báňské projekty in Teplice filed a joint application with the Ministry of Culture in 1982 calling for cancellation of the heritage conservation status of Jezeří Chateau and the adjacent Ore Mountains hillsides.
Dr Marek learnt about the meeting called by the Ministry of Culture to discuss the matter the night before during a discussion with Ing. Stoklasa at the “Quite Small Theatre” in Litvínov. Following a discussion weighing up the relative importance of the coal on the one hand and the local landscape, cultural heritage and health of the population on the other, which carried on until midnight, he set off for Prague in his 4WD. He was going to wash and change at home and attend the crucial meeting the next morning. On the way, driving through a February night snowstorm, he missed the elevated on-ramp leading to the new bypass at Panenský Týnec and crashed into a ditch. He left the overturned car through the rear window before the running engine exploded and the car caught fire. He managed to explain the accident to the Louny police, catch the first bus to Prague from Louny, attend the meeting at the Ministry, and take part in the discussion. The miners’ proposal to lift the conservation status of Jezeří and expand the mining district up to the summit portions of the Ore Mountains was not approved.
However, the meeting had a tragic aftermath: Ing. Kašpárek, director of the Regional Office of State Cultural Heritage and Nature Conservation in Ústí nad Labem, had a heart attack and died the next day.
Proposal to demolish Jezeří ignites widespread debate
The miners’ plan to destroy Jezeří Chateau and the adjacent mountainsides provoked a long-lasting and frequently passionate polemic in the daily press and other media as well as at various professional conferences over the period 1981-1987.
Disapproving positions were expressed by leaders in culture, history, nature and heritage conservation, representatives of the local population, youth environmental movements, and journalists alike. Dr Marek initiated the production of a monographic issue of the popular journal “Památky a příroda” [Monuments and Nature] dedicated to the Jezeří issues. It was published in 1983, and the editors still refused to include a paper by Dr. Líbal, the country’s leading expert on heritage buildings, who resolutely defended the conservation of Jezeří.
The village of Albrechtice fell prey to the mining preparations below Jezeří in 1985. As was the custom in the area, the houses to be demolished were looted. At that time, Dr Marek’s colleagues and he were arrested at Jezeří and charged at Most police station with lotting the chateau. The event was probably stage-managed by mining lobbyists. A lengthy report was made after a long interrogation; no prosecution followed but he was still stalked by the police even at home in Prague.
In the eyes of the mining authorities, Jezeří Chateau was becoming an increasingly hated structure, allegedly an obstacle to further advances in coal mining, although it is situated outside the coal seam. The official caretaker of the building – the Regional Conservation Office in Ústí nad Labem, which had no means even to do basic maintenance – was reluctant to invest its limited resources in a building endangered by demolition, the proposal for which had already been made. It made several efforts to get rid of the dilapidated building: by assigning it to the mine corporation! It even dismissed the only employee – the chateau custodian. Therefore, the presence of Dr Marek and his six colleagues in the field office, which they refused to abandon, was the only obstacle to carrying out the demolition plan.
The Jezeří issue reaches a wider international and national audience
In the meantime, the Jezeří issue made it into an international forum. It was talked about at geological, hydrogeological, engineering geological and geotechnical conferences all over the world (Melbourne, Washington, Nuremberg, Granada, Moscow, etc.), but mostly by others. After Dr Marek submitted his final research report, there were suddenly scores of ambitious experts willing to declare the results, conclusions and interpretations as their own, and boast about them abroad. Dr Marek was not even allowed to read out my paper at the World Geology Congress in Moscow in 1984. However, he produced a short film about the stability issues of the Ore Mountain slopes due to the coal mining for Washington D.C. and a paper on a similar issue for Melbourne. Ing. arch. Zdeněk Stáhlík of Terplan and he became expert advisors for another, more artistic short film on the issues around Jezeří and the Ore Mountains.
During the harsh political “Normalization” period, however, positions published in “Rudé právo” – the leading press medium of the all-governing Communist Party – were the most significant ones. Editor Jindra Čekalová played an exceptional role there. She was not afraid of publishing opinions that clearly went against the existing ideological positions and guidelines of the ruling Party, whether under her own name or signed by apparently non-conforming individuals, irrespective of the disapproval of the then editor-in-chief, comrade Kojzar, and at the risk of her own existence.
Editors of dailies and popular periodicals visited the critical area around Jezeří as a group in 1985. The editorial office of “Věda a technika mládeži” celebrated Dr Marek as the winner of a nation-wide competition of discoverers and inventors.
The regime finally begins to change its stance
Party officials agree to limit mining and preserve the chateau
Regional, district and municipal secretaries of the Communist Party made a field trip to the Jezeří area in 1986 with the aim of giving political support and assurance to the uninterrupted operation of the coal mining. Rudé právo editor Čekalová elbowed her way into the field trip (and could not be refused due to her position), and brought Dr Marek along as her expert advisor (otherwise he could not have attended such a meeting, being a branded opponent to the regime). He provided the board of secretaries with a comprehensive explanation of the issue, took them to the dam of the then emptied Lake Dřínov, guided them around the derelict chateau, and attended the final discussion at the House of Culture in Most. Of the 12 Party exponents originally biased in favour of continuing the coal mining, eleven eventually voted for limiting the mining and preserving Jezeří Chateau. Comrade Šenkýř, a regional Party secretary, formulated the final statement.
Deputy Prime Minister Rudolf Hegenbart, a pro-reform secretary of the Central Committee of the Communist Party and head of the Interdepartmental Committee, visited Jezeří in 1987. He arrived with several ministers and in the company of the General Manager of North Bohemian Mines, dressed in an incomplete miner’s uniform. On the terrace of the chateau, overlooking the coal basin, he listened to the General Manager’s lecture on the mining progress, continuing success and bright prospects for the coal mining. Then he listened to Dr Marek’s lecture. After that, he asked him for his published works to study and kept holding on to his elbow throughout the rest of the guided tour. Before the end of the excursion, he made Dr Marek sit in one of the two chairs available in the chateau courtyard, sitting himself on the other one, while the team of ministers and the General Manager of the mine corporation had to look on standing in a semicircle around them. Everyone present must have been clear about the fact that the decision had been made.
The Central Party Committee concurs
There was no doubt that Hegenbart then had to overcome the opposition of the conservative members of the Central Party Committee and negotiate with representatives of the international Comecon, directed from Moscow. No definitive and formal decision was arrived at for a long time. That was why Dr Marek appeared on the popular TV show “Vysílá studio Jezerka” in October 1987 and demanded a political decision. The response of the Prague Municipal Committee of the Communist Party was rancorous, and he was again deleted from the list of nominees for State Awards. Jana Fořtová, the TV show host, preferred emigration. Nevertheless, the government’s decision was published in the spring of 1988: Jezeří Chateau would be preserved and renovated. The coal mine had to ensure the stability of its underlying slope. The Government earmarked special lottery funds for the renovation.
The mine managers and planners were thus forced into a solution they did not welcome: they had to leave intact the portions of the basin strata series below the most critical parts of the main Ore Mountains side, including the coal seam, which could not be extracted through an opencast mine. Those areas were to act as pillars whose purpose was to secure the stability of the tectonically disrupted mountainsides and thus the safety of operations in the open mine pit. The pillar below Jezerka contains approx. 10 million tonnes of coal; the one below Jezeří has 20-30 million tonnes of coal. Naturally, the pillars and their surroundings had to be kept under geomechanical and geodetic monitoring. The village of Albrechtice could not be saved: it had been destroyed shortly before that (quite pointlessly, as it turned out).
The new struggle to maintain the chateau
The victorious celebrations quickly gave way to having to sort out who would undertake the overall renovation of the intricate building. A bid was made by Průmstav Pardubice, a Chomutov operation, a large and well-established company, but its general manager forbade the commission. The first money that arrived in the Jezeří account was used for erecting a metal scaffold around the main building, and a small construction team from the Žalany u Teplic co-operative farm started fixing the roof. When they found out it was beyond their capacity, they passed the task on to the Most state farm.
A small group of persistent campaigners to save Jezeří with a larger circle of supporters established itself as the “Association to Save Jezeří” in 1988. It registered itself with the Ministry of the Interior when a mild political thaw came. Later on, the citizens’ association name was changed to the “Association to Restore Jezeří” in order to better express its current goals and efforts. The purpose was not only to save the historic building but also to restore its surroundings and the remains of the original landscape. A notable paradox then occurred: the Association exponents who were experts on various scientific disciplines and land use, who were previously in opposition to the governing political team, now became an informal advisory board to the Secretary of the Central Committee of the Communist Party! The one who took up the task of resolving the long neglected and truly pressing environmental problems: Rudolf Hegenbart. Associations members were summoned as needed and met in Prague, usually in the Terplan basement. An exceptional meeting was held in the little-known Ore Mountains hamlet with a long mining tradition, Hora Sv. Kateřiny, in October 1988, when they celebrated the birthdays of the environmental activist Petr Pakosta as well as Dr Marek.
The collapse of the communist regime: the context to rescue the chateau changes again
Soon afterwards, however, the party and government began to break apart and collapse in November 1989. That had serious implications for Jezeří. The former all-governing position of North Bohemian Mines lost its political support and, soon after that, its economic power. They were forced to reduce the mining activities to a fraction of the previous volume, making the advance of the Czechoslovak Army opencast mine slower. They had to start acting at least a little “environmentally”, since that was the universal imperative of the new era.
Jezeří attracts high profile visitors
Jezeří was receiving increasing visits by new statesmen, ministers, deputies, Prime Minister Petr Pithart, and President Václav Havel. William Lobkowicz, the grandson of the last pre-war owner, arrived from the USA in 1990, took up permanent residence in Prague and requested the chateau be returned to him. One of my colleagues at Jezeří, Dr. František Jeniš, left for an expedition called “Driving a Tatra Round the World” and died in the mountains of Pakistan.
In 1991, Prince Charles and Princess Diana made their first official visit to Czechoslovakia. The schedule for the end of the visit by the pro-environmental Prince, arranged with the Presidential Office, included a visit to the Most district, marked by large-scale destruction due to coal mining, and Jezeří Chateau, which had barely escaped its demolition order. Princess Diana left for England, and Prince Charles and his entourage arrived by plane – piloted by the Prince himself – at the disused military airfield at Žatec. In place of President Havel, he was accompanied by Chancellor Schwarzenberg, the British Ambassador, Federal Minister of the Environment Josef Vavroušek, Czech Minister of the Environment Ivan Dejmal, and journalist Pavel Tigrid. During the tour of the coal basin, Dr Marek gave a general lecture on the dam of Lake Dřínov and the body of the cut-off road below Jezeří. Then the convoy arrived at Jezeří, where the Prince was welcomed by Parliamentary Chairman Milan Uhde and the Lobkowicz family in the upper garden. Dr Marek presented an overview of the chateau history in the courtyard, and the terrace overlooking the mine pit provided the guests with a vista of the gaping mine pit and the country that was being devoured by the demanding power industry. The Prince was sincerely shocked. After Dr Marek introduced the activists of the Association to Restore Jezeří, he said, “I do not envy your job,” and registered himself as a member of the Association. So did Milan Uhde and Pavel Tigrid.
Of course, the regional, national and international media informed the public about the visit. Only after that could the Jezeří area and its adjacent mountainside be considered to be saved in the new political era: the topic had been made popular enough by the media.
The Prince promised to contribute towards the restoration of Jezeří with money from global funds. In order to be able to accept any such donations, the Association to Restore Jezeří set up the Foundation to Restore Jezeří with the economist Ing. Jaroslav Stoklasa as the chairman, and opened an account with a bank in Most. The first deposit was made by the Prague-based architect Karel Císař, who designed the chateau renovation project. No other money arrived, though. The Prince kept his promise, but the money never made it past Prague. It was used for renovating the Baroque gardens under Prague Chateau and perhaps the replacement of several of the Charles Bridge statues. Money from the special funds, allocated by the State through the Regional Authority, only kept arriving until its dissolution in 1993. Then it dried up.
Through Ing. Stoklasa, who had become an advisor to Minister Vavroušek in the meantime, the Association tried to promote the idea of making Jezeří a national centre for studies of possible rehabilitation of extremely damaged landscapes. Something similar exists in Austria, where the state has given Chateau Laxenburg, confiscated from the Habsburgs, to international environmental projects. Ing. Stoklasa brought up the proposal in various ministerial and environmental circles, including abroad, but did not succeed.
Limits placed on mining operations in the North Bohemian coal basin
Territorial limits to the mining of brown coal in North Bohemia was approved in parliament in 1991 through the binding resolution of the government of the Czech Republic No. 444, which was passed at the instigation of the then Minister of Environment Ivan Dejmal. It defines the mining areas where coal reserves have been written off.
The main reason for the setting of the limits was to protect the environment and landscape in the North Bohemian region. The limits serve as a government guarantee to North Bohemia districts that henceforth their environment would not continue to deteriorate and that their long-term existence was assured (i.e. that it was worth purchasing property there, building and repairing houses, reconstructing roads, setting up businesses, etc…).
The limits also served to provide confidence to those wishing to protect, preserve and repair Jezeří Chateau as there would no longer be any prospect of encroaching mining operations undermining the slopes of the Ore Mountains upon which the chateau rests.
Problems with funding of maintenance and ownership
Jezeří Chateau was no longer an exception as a heritage building saved just prior to destruction under the new political conditions. Other regions too began making claims on funds for renovating their dilapidated heritage buildings, such as Brno did for Špilberk. Faced with such a situation, the government gladly complied with former owners’ claims, and restored Jezeří Chateau to the Lobkowicz family.
The former economic hinterland for the chateau – the Jezeří and Nové Sedlo nad Bílinou dominion – fell prey to large-scale coal mines. The restituted owners were given no compensation for it. Only the forest properties in the Ore Mountains remain; they had been degraded due to the pollution and climate change resulting from coal combustion in power plants. They were given back about 10 more buildings, mostly in a devastated condition and without their economic hinterland. They soon concluded they could not sustain Jezeří. William Lobkowicz offered to transfer the chateau to the Association free of charge. Dr Marek had to decline that generous offer politely, both for himself and on behalf the Association that he chaired. It was unclear how they would provide the dilapidated building with security, fire safety, drinking water and other essentials. None of them had enough money for renovating it.
Some risk emerged at the other end: The Lobkowicz family were in dire need of funds for renovating their other restituted properties. In order to raise some funds, they offered Jezeří Chateau for sale. Given the situation resulting from the coal mining, it was obvious that the coal miners would be the only potential buyer. The intention would not be to locate their managerial offices in it or convert it to a holiday resort for their workers, but to finally erase the despised building. No one could prevent them from doing so as the legitimate owners, meaning all the previous efforts to save it would be in vain.
So the Association had to fight on. Dr Marek approached the Lobkowicz family with a long letter in which he invoked their moral obligation towards the building that they had owned for more than 300 years, and its liability for the history of the Czech lands, in which it often interfered significantly from its seat at Jezeří. Dr Marek argued that the chateau must not be sold but returned to state ownership. The old Czech nobility obeyed! The government authorities had to be convinced again that they ought to take over the building, which they had left to rot, and complete its renovation. It was not easy, but it worked. The case was partly supported by Dr Marek’s reputation in heritage and environmental conservation circles, partly by the fact Milan Uhde and Pavel Tigrid were members of the Association to Restore Jezeří, and definitely by Prince Charles’s visit.
Nevertheless, Prince Charles was not the only royalty to visit Jezeří. In another official state visit, Queen Beatrix of the Netherlands and her husband, Prince Klaus, arrived in the company of the Dutch Ambassador, Chancellor Dobrovský and Minsters Dlouhý and Benda in 1994. As part of the Presidential Office plan, the welcome in the chateau garden was be followed by a view from “Charles’ Vista” and a presentation by the North Bohemian Mines manager. Local environmental activists protested against that. They convinced Chancellor Dobrovský that the presentation should only be made by Dr Marek. The mine manager would then be allowed to boast the mining successes in the basin below. Dr Marek handed the Queen the commemorative essay “Krušné hory, Jezeří and related matters” and a handful of raw Bohemian garnets. The Queen said she “would like to be as helpful as possible in saving Jezeří and the landscape”. Unfortunately, her willingness was not exploited as a result of an avalanche of other events. Ministers Benda (environment) and Dlouhý (industry and trade) said nothing and would make no perceptible effort for Jezeří later on.
The battle is won and restoration work begins
Following the exceptional case of the State taking back over a property that had been restored to its legitimate owner, the State invested some money in its renovation, but far less than the demanding project required. So work proceeded only slowly. Nevertheless, several years later, one can appreciate that the chateau gleams in the distance with its new roofing, repaired chimney heads, copper-plated cupolas, and gilded balloons on the spires. Parts of the chateau have been made accessible to the public. The warden is Hana Krejčová, a local and a former singer at Teplice Theatre, who has a welcome attachment to the place and the chateau. We may yet see the renovation completed.
The Foundation to Restore Jezeří has been dissolved. The Association to Restore Jezeří has not, and although the effort to restore Jezeří has been accomplished, there are still problems in which it has to be involved or which it has to take up under pressure of current events. Although there are no regular meetings, the Association is still capable of mobilizing its active core members and apply its font of knowledge and experience wherever it is needed.
The saving of Jezeří was a battle won among the several large battles that individuals and environmental groups waged against megalomaniacal projects promoted by the Party and those in power at the time. They prevented the construction of a large dam on the Berounka near Chateau Křivoklát and a high-rise hotel on the top of Sněžka (the highest peak in the Czech Republic). The only thing they failed to prevent was the development of a car racing circuit in a suburban forest near Brno, which totally ruined the notion of the idyllic setting of the writer Alois Mrštík’s “May Fairytale”. That can be regarded as a fair success during the totalitarian era.
Jezeří is made publicly accessible again
Jezeří Chateau was opened to the public again in June 1996. Given the state of the monument, a whole range of provisional arrangements were made to enable basic viewing. There weren’t many options for exhibiting the chateau, and so in making it accessible it was necessary to overcome many various technical obstacles. It was necessary to delineate the best preserved part of the entire premises that wouldn’t represent a safety risk to visitors. The most suitable solution proved to be making several rooms partially accessible in the northern part directly connected to the chateau gardens whose main gate was used for providing temporary access to the grounds. In 1996, two rooms were made accessible – the small salon and a bedroom with direct access to the chateau gardens, where a small wooden outbuilding was also used for selling tickets and souvenirs. The tour itself included only a commentary on the chateau’s history and the showing of a short documentary film about the chateau’s history and surroundings because the chateau was completely empty of any fixtures. The second part of the tour was of the cellars and chateau silversmith workshop. After several years, the tour circuit expanded to a further three rooms and in the northern tower where a labelled exhibition of the 19th century interior was installed with a look at how the building was used for hunting purposes in the past. An inventory from the National Heritage Institute depository in Ústí nad Labem was used for this exposition, while supernatural creatures and fairy-tale characters were installed in the cellars.
Tours of the building take place at the same time reconstruction work is being carried out so that the chateau management is forced to adapt to situations as they arise. An important change in the tour circuit resulted from the erosion of the painted timbered ceiling on the second floor of the northern tower when it was necessary move the inventory and look for another suitable type of tour circuit. This happened in January 2004. Given that partial reconstruction of the ground floor of the lord’s manor had been completed, which permitted the use of this space for a cash desk and facilities for visitors, the entrance to the chateau was able to be moved from the inner forecourt. The inventory was moved to the southern part of the chateau, which had already been stabilised by the reconstruction work undertaken on the roof and ceilings.
