We made a special trip to Lorient to visit this WWII museum. It was built by the Germans to build and store submarines for fighting the Allies in WWII. They have guided tours which you can pre book. Unfortunately, the guides do the tours in French, so unless you understand French (or have someone with you who can translate) it can be a bit hard to get the history of the place.
The building is massive and is built with reinforced concrete to withstand the bombs that the Allies dropped on it on a regular basis. The guide takes you to the top floor to show where a bomb made a bit of headway and you can see how thick the walls and ceilings really are. They take you on the roof, which gives you an amazing view of the harbour and town and for a tour of the submarine pens.
If you like history and have a special interest in WWII or submarines, this is a great place to spend a few hours. read more
