Bock Casemates
UNESCO World Heritage
Carved into the sandstone of the Bock promontory, these 17 kilometres of underground galleries form the surviving heart of Luxembourg City's vast fortification system, first excavated by Spanish engineers in 1644 and later extended by Vauban and the Austrians. The above-ground walls were demolished under the 1867 Treaty of London, but the subterranean passages proved too extensive to destroy safely, leaving an extraordinary labyrinth now open to the public. Together with the old quarters, the casemates form part of the UNESCO World Heritage Site inscribed in 1994.
