Between underground history and urban treasure hunting in Luxembourg!
After several years of closure, the Bock Casemates in Luxembourg are finally open to the public once again! These incredible tunnels, which had been closed for nearly three years, are now ready to welcome visitors eager for history and culture. This architectural and historical gem in the city of Luxembourg is once again accessible to both locals and tourists.

The Bock Casemates are a network of tunnels and underground fortifications located in Luxembourg City. Originally built in 1644 during the Spanish rule, they were expanded and reinforced over the centuries by the French, Austrians, and eventually the Luxembourgers themselves. These casemates served as shelters, barracks, and workshops and played a crucial role in defending the city. With more than 23 km of tunnels, the Bock Casemates have been listed as a UNESCO World Heritage Site since 1994 and offer a fascinating window into European military history.
Since their reopening, the Bock Casemates have seen an extraordinary surge in popularity, according to an article in L’essentiel. Visitors from around the world are flocking to explore these impressive structures and immerse themselves in their rich history. Reviews have been overwhelmingly positive, and the reopening has clearly filled a cultural gap in the city’s tourist attractions.
