The flak tower is not barrier-free due to the structural conditions. There are numerous stairs, some of which are steep.
Monstrous flak towers were built in the 1940s as a defence against Allied air raids and as a shelter for the population. Most of them were demolished after the war. The Humboldthain Flak Tower had long been buried under a mountain of rubble until the association Berliner Unterwelten e.V. made it accessible again to the public in 2003.
