Bock Casemates: a UNESCO World Heritage Site
The Bock Casemates, a subterranean defence system made up of kilometres of tunnels, is today one of the most important visitor sites in Luxembourg. These underground galleries were initially carved in the 17th century, under Spanish rule, and subsequently twice extended. Visiting the archaeological crypt, the antechamber to the casemates, is a similarly remarkable experience. On account of these impressive fortifications, Luxembourg was even given the epithet of the “Gibraltar of the North”. Discover the tumultuous history of the casemates and take in wonderful views of the Grund, Clausen and Pfaffenthal districts.
