Luxembourg: The Bock Casemates In 963, Count Sigfried built a castle on the Bock Promontory, which became the beginnings of the later city of Luxembourg. In the middle of the 18th century, the Austrians began to build the Bock Casemates. These impressive defences provided a refuge for the citizens and this underground fortress became known as the "Gibraltar of the North". The archaeological crypt, didactic antechamber of the casemates, was an additional highlight of our visit, but it was deep caves, punctuated by openings in the sheer cliff wall that became the focus of these photos. In 1994, they were inscribed on the UNESCO World Heritage List.
