A place Looking to the Future

Built by the Germans during the Second World War, this base sheltered German submarines (U-Boats) during the Battle of the Atlantic. After the Liberation, the base was taken over by the French Navy, who left it in 1997.

Starting in the 2000s, the site was successfully repurposed. It is now a very important economic, tourist and nautical hub (Eric Tabarly Sailing museum, Submarine Flore and its museum, submariners’ museum du Pays de Lorient, ocean racing centre, the contemporary music concert hall (Hydrophone…).

Guided tours to discover an exceptional place

With an experienced professional guide, explore the most important submarine base built by the Germans during the 1939-1945 war. You will discover Lorient, the strategic base of the Battle of the Atlantic. Learn everything about the construction, operation and history of the base: and you get to visit the K3 block, the largest of the bunkers.

Good to know: access to the roof of K3 is up a long, quite steep staircase. If you don’t want to climb, you can wait downstairs during the 20-minute visit on the roof.
