The Bock is a promontory in the north-eastern corner of Luxembourg City's old historical district. Offering a natural fortification, its rocky cliffs tower above the River Alzette which surrounds it on three sides. It was here that Count Siegfried built his Castle of Lucilinburhuc in 963, providing a basis for the development of the town which became Luxembourg. However, the Romans and later Franks had probably already inhabited the Bock although there is only scant archeological evidence of their presence. There are however traces of a 4th-century Roman watchtower close to the point in the Fish Market where two major Roman roads used to cross, one from Reims to Trier and the other from Metz to Liège.
Over the centuries, Siegfried's fortified castle on the Bock was considerably enlarged and protected with additional walls and defences. In 987, the castle chapel was built at the nearby Fish Market. Today's St Michael's Church stands on the same site. Under Conrad I, the castle became the residence of the Counts of Luxembourg. It was damaged, destroyed, captured and rebuilt on several occasions as the Burgundians (1473), the Habsburgs (1477), and the Spaniards (1555) attacked and took the fortress.
As time passed, the fortifications needed to be adapted to new methods of war based on increasingly strong firepower. During the 1640s under the Spaniards, the Swiss engineer Isaac von Treybach significantly reworked the defences. The Bock was also strengthened with three forts, the Large Bock, Middle Bock and Small Bock (from west to east), separated from each other by cuts in the rock and linked by bridges. As a result, little remained of the medieval castle.
A little later in 1684, on behalf of Louis XIV, Vauban succeeded in capturing the city of Luxembourg during a month-long siege under which the Bock fortifications were completely flattened. Thereafter Vauban, perhaps the most competent fortification engineer of his day, undertook major additions to the defences, realizing that underground passages and chambers were just as important as the surface installations. The Large Bock, connected to the old town by the Pont du Château, was further reinforced. Enclosed by a wall 12 m high, it was the major component of the new fortress.
In addition to these structures, the Bock also included a system of casemates which originated in the cellars of the medieval castle. In 1744, during the Austrian period, these underground passages were considerably enlarged by General Neipperg. The main passage. which still remains, is 110 m long and up to 7 m wide. Branches leading off on either side were equipped with no less than 25 cannon slots, 12 to the north and 13 to the south, offering considerable firepower. In the event of war, the Bock casemates, covering an area of 1,100 m2, could be used as barracks for several hundred soldiers.
Thanks to its defences, in 1794 during the French Revolutionary Wars, the city held out against the French siege for seven months. When the garrison finally surrendered, the walls were still unbreached. The fortifications were finally demolished under the terms of the Treaty of London in 1867. The demolition took 16 years and cost the enormous sum of 1.5 million gold francs.
In 1933, the Bock casemates were opened to the public. During the Second World War, they were used as a bomb shelter able to accommodate up to 35,000 people. In 1994, the casemates were added to the list of UNESCO's world heritage sites, attracting some 100,000 visitors a year. Renovation work and repairs were undertaken in 2008–2009 including the opening up of the mine galleries which contained explosives able to blow up part of the Bock in case of need.References:
The original Cochem Castle, perched prominently on a hill above the Moselle River, served to collect tolls from passing ships. Modern research dates its origins to around 1100. Before its destruction by the French in 1689, the castle had a long and fascinating history. It changed hands numerous times and, like most castles, also changed its form over the centuries.
In 1151 King Konrad III ended a dispute over who should inherit Cochem Castle by laying siege to it and taking possession of it himself. That same year it became an official Imperial Castle (Reichsburg) subject to imperial authority. In 1282 it was Habsburg King Rudolf’s turn, when he conquered the Reichsburg Cochem and took it over. But just 12 years later, in 1294, the newest owner, King Adolf of Nassau pawned the castle, the town of Cochem and the surrounding region in order to finance his coronation. Adolf’s successor, Albrecht I, was unable to redeem the pledge and was forced to grant the castle to the archbishop in nearby Trier and the Electorate of Trier, which then administered the Reichsburg continuously, except for a brief interruption when Trier’s Archbishop Balduin of Luxembourg had to pawn the castle to a countess. But he got it back a year later.
The Electorate of Trier and its nobility became wealthy and powerful in large part due to the income from Cochem Castle and the rights to shipping tolls on the Moselle. Not until 1419 did the castle and its tolls come under the administration of civil bailiffs (Amtsmänner). While under the control of the bishops and electors in Trier from the 14th to the 16th century, the castle was expanded several times.
In 1688 the French invaded the Rhine and Moselle regions of the Palatinate, which included Cochem and its castle. French troops conquered the Reichsburg and then laid waste not only to the castle but also to Cochem and most of the other surrounding towns in a scorched-earth campaign. Between that time and the Congress of Vienna, the Palatinate and Cochem went back and forth between France and Prussia. In 1815 the western Palatinate and Cochem finally became part of Prussia once and for all.
Louis Jacques Ravené (1823-1879) did not live to see the completion of his renovated castle, but it was completed by his son Louis Auguste Ravené (1866-1944). Louis Auguste was only two years old when construction work at the old ruins above Cochem began in 1868, but most of the new castle took shape from 1874 to 1877, based on designs by Berlin architects. After the death of his father in 1879, Louis Auguste supervised the final stages of construction, mostly involving work on the castle’s interior. The castle was finally completed in 1890. Louis Auguste, like his father, a lover of art, filled the castle with an extensive art collection, most of which was lost during the Second World War.
In 1942, during the Nazi years, Ravené was forced to sell the family castle to the Prussian Ministry of Justice, which turned it into a law school run by the Nazi government. Following the end of the war, the castle became the property of the new state of Rheinland-Pfalz (Rhineland-Palatinate). In 1978 the city of Cochem bought the castle for 664,000 marks.
