Flakturme ( Flak towers )referred to several bunkers , which were built during the Second World War in Berlin, Hamburg ( Germany ) and Vienna ( Austria ) for anti-aircraft guns ( Flak ) and their fire control systems and were also used as shelters.
The Flak Tower IV in St. Pauli was designed as high bunker with mounted air defense guns The second function, protection of the population in air raids, could fulfill the towers, because the dropped explosive bombs could not penetrate the 5 meter-thick walls and ceilings, even if they hit directly.
construction goes down in history as the largest bunker ever built on European soil,
They had an armament of four 10.5 cm anti-aircraft guns, which were replaced in August 1942 by four 12.8 cm Flakzwilling 40 and numerous smaller caliber guns, mostly quadruple 20 mm AA guns . The Flakturm IV is one of the largest bunkers ever built. The base measures 75 meters x 75 meters, with 38 meters high. The wall thickness is 3.5 meters the ceiling is five meters thick. Windows were installed and sealed with concrete seals. Although capacity was limited to 18,000 people ( including a hospital with 95 beds.) , during the heavy air raids on Hamburg in the summer of 1943, up to 25,000 people sought shelter in the bunker.
