Bunker Vault d'Arthur

Bunker Vault d'Arthur is a concrete structure at the base of Cap Ferret lighthouse, featuring painted camouflage on its exterior walls and multiple interior compartments. The structure contains various chambers designed for military operations and personnel.

The structure was built in 1943 by Organization Todt as part of the Atlantic Wall defense system and served until troops departed in 1944. It formed part of a larger coastal fortification network stretching along the French Atlantic coast.

The bunker displays reconstructed living spaces from 1944, giving visitors a direct view of how soldiers spent their daily lives during World War II. You can see the cramped quarters where men slept, cooked, and worked together.

The bunker is located within the lighthouse park and can be visited during lighthouse hours. Tour groups are guided through the structure by members of the GRAMASA association.

The structure features a wooden cabin built on its roof, which along with painted facade details was designed to fool enemy aircraft during reconnaissance missions. These camouflage techniques reveal how defenders tried to disguise the bunker's true purpose and location.
