The Bunker Valentin is the ruin of a submarine shipyard of the German Navy from World War II. Covering more than 35,000 square metres, it is the largest free-standing bunker in Germany. From 1943 to 1945, thousands of forced labourers from all over Europe were put to work here: civilians, prisoners-of-war and concentration camp inmates. More than 1,100 people died during construction from starvation, illness and arbitrary killings.
Over a period of five years, the grounds of the memorial were redesigned and opened to the public in November 2015. An information trail with 25 stations tells the history of the bunker with historical photos, eyewitness accounts and short explanatory texts. The route begins at the memorial “Annihilation through Work” and continues into the visitors centre and on to the other stations on the grounds. More in-depth information is provided by the exhibition, a media table with projections and a multimedia guide, which is available for loan free of charge.
