4,000 people died in the construction of Hitler’s Submarine Bunker
The submarine bunker is gigantic — and expensive. A World War II-era military facility is slowly succumbing to the elements, and nobody seems willing to pay for its upkeep. In fact, the German armed forces has offered it for sale.
The bunker Valentin was built by the Nazis as a bomb-proof submarine factory. It never went into use, but 4,000 slave laborers, concentration camp inmates and prisoners of war died in its construction. More photos after the jump.
