Keroman Submarine Base, Lorient

4.5
#4 of 8 in Museums in Lorient
Keroman Submarine Base was a German U-boat base located in Lorient during World War II. Großadmiral Karl Dönitz decided to build the base on 28 June 1940. Between February 1941 and January 1942 three gigantic reinforced concrete structures were built on the Keroman peninsula. They are called K1, K2 and K3. In 1944 work began on a fourth structure. The base was capable of sheltering thirty submarines under cover. Although Lorient was heavily damaged by Allied bombing raids, this naval base survived through to the end of the war. Lorient was held until May 1945 by the Germans' Wehrmacht Heer regular army forces, though surrounded by the American Army; the Germans refused to surrender.Since they could not destroy the base and its submarine pens, the Allies had decided to flatten the city and port of Lorient to cut the supply lines to the U-boat bases. Without resupply of fuel, weapons (e.g. torpedoes), and provisions, it became impossible for those U-boats to return to war patrols in the Atlantic Ocean. Between 14 January 1943 and 17 February 1943, Allied aircraft dropped as many as 500 high-explosive bombs and more than 60,000 incendiary bombs on Lorient; nearly 90% of the city was flattened.

  • This was a brilliant family day out we will never forget. My advice is to get a guided tour, our English speaking guide was so knowledgeable about the place without him we would have walked past so much incredible history without even knowing. The diver training museum was interesting enough with English translation I pads to carry around but it was definitely the human touch with the guided tour around the submarine pens that made the day for us.
  • As most things are, a matter of taste, but our tour guide—French, but the tour was in English—did a great job of explaining the technical and historical aspects of the base. Even without a tour (we didn’t have time to tour the inside of the submarine itself but still found our tour satisfying), it’s a neat place to walk around and explore.
