Stock Photo - In the parts of the submarine bunker Valentin, which can be rented privately today, often vintage vehicles are stored, here winters under a protective hood obviously an American street cruiser, taken on 11.08.2018. The submarine bunker Valentin in Bremen-Farge was built on a surface of more than 3.5 hectares in the years 1943 to 1945 by forced laborers, making it the largest freestanding bunker in Germany. In this important armament project of the German Navy naval submarines of type XXI were to be manufactured in section construction. After the World War, the Federal Navy used parts of the site as a material store until 2010, and in the years 2011 to 2015, a visitor center with the memorial site Denkort Bunker Valentin was created, in which thousands of forced laborers have been sentenced to death.
