Base de Sous-Marins Keroman

Base de Sous-Marins Keroman Review

Built by the Nazis during World War II, this submarine base is the world's largest 20th-century fort. Thirty submarines could be comfortably housed in the squat concrete bunker—and its 27-foot-thick roof withstood intensive Allied bombing virtually intact. Open year-round; call ahead to be part of a 90-minute tour.
