This underground bunker was built in 1942 to offer shelter to 2702 people. Like other bunkers in Hamburg, it was renovated in the 1960s and fixed up as a civil-defence-room for the Cold War. It is divided into a northern and a southern wing. The longest corridors measure about 80 meters. On all three levels there are rows of seats with luggage racks or bunk beds fitted into the rooms. These can be disassemble when require.
