Stadtgebiet Bremen, Italy
The Valentin submarine factory is a protective shelter on the Weser River at the Bremen suburb of Rekum, built to produce and launch German U-boats during World War II. Built between 1943 and March 1945 using forced labor, the factory sustained damage from air raids before U-boat production could co
mmence. It was the largest fortified U-boat facility in Germany, second only to the facilities at Brest in France. As a manufacturing facility, it differed from conventional U-boat pens, which were designed for housing and servicing operational U-boats.
