Fodor's 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. Ninety-minute tours begin at 3 pm daily in summer and on Sundays year-round.
