Reviews Summary
Visitors praise La Base Keroman for its impressive WWII German submarine pens and the fascinating tour of the French submarine Flore, calling it a 'great place to visit' for history buffs.

"Together with La Rochelle one of the best examples of surviving German WWII concrete Bunker constructions, in this case the U Boot pens were built so as to withstand direct hits by allied bombers.
A great place to visit if you are a WWII historian/buff particularly interested in submarine warfare and bunkers."

"They only run tours so pre booking is required. A good story on the building and how the people survived etc.
Also there is a good kids playground along the pier front."
