Casemates du Bock
In 963, Count Sigfried built a castle on the Bock Promontory, the foundation stone of the later city of Luxembourg. In the middle of the 18th century, the Austrians began to build the Bock Casemates. These impressive defences give a better understanding of the great fortress machinery that was the "Gibraltar of the North". The archaeological crypt, didactic antechamber of the casemates, is an additional highlight of the visit. No wonder that the fortress bulwarks and the old town, no less steeped in history, enjoy worldwide renown. In 1994, they were inscribed on the UNESCO World Heritage List.
