The Saint-Nazaire U-boat bunker is one of five German U-boat bases built on the French Atlantic coast during World War II. The 301-meter-long bunker was built in just 16 months in 1941/42 using almost half a million cubic meters of concrete. Several hundred men were stationed here until May 1945; offices, workshops, and a medical center were housed under the roof, which was up to 9.60 meters thick. It was built on the site of the former overseas port from which steamers departed for Central America.
