Object description

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. Ruins of the old castle and the vast underground system of passages and galleries known as the casemates continue to be a major tourist attraction.
