Casemates of Boc

Casemates du Bock

Casemates du Bock is a labyrinth of galleries and underground corridors totaling 23 km, carved by the Spanish under the ledge of the Bock cliff in 1644. There was once a castle on this rock around which Luxembourg was built, but it was destroyed in the 19th century by the Treaty of London and the casemates are all that remains of it.

General information

At various times Bock Casemates housed bakeries and abattoirs, and during the Second World War the casemates served as a bomb shelter. Since 1994, the Bock casemates have been included in the UNESCO World Heritage List.

The casemates are open to the public from March to October, open daily from 10.00 to 17.00, admission costs €3, children €2.50.
