Bock Fortifications

Luxemburg, Luxembourg

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.

The tour around Casemates du Bock would be more complete by walking around the gardens surrounding it. The surrounding of the fortification is enhanced with greenery and splendid views which makes the city of Luxembourg a beautiful landscape.

Monet's Garden

Claude Monet lived for forty-three years, from 1883 to 1926, in Giverny. With a passion for gardening as well as for colours, he conceived both his flower garden and water garden as true works of art. Walking through his house and gardens, visitors can still feel the atmosphere which reigned at the home of the Master of Impressionnism and marvel at the floral compositions and nymphéas, his greatest sources of inspiration.

In 1890 Monet had enough money to buy the house and land outright and set out to create the magnificent gardens he wanted to paint. Some of his most famous paintings were of his garden in Giverny, famous for its rectangular Clos normand, with archways of climbing plants entwined around colored shrubs, and the water garden, formed by a tributary to the Epte, with the Japanese bridge, the pond with the water lilies, the wisterias and the azaleas.

Today the Monet's Garden is open to the public.
