Tour 2 – From Flak Towers to Mountains of Debris Enter a devastated albeit fascinating underground world
In 1940, Hitler ordered the construction of six anti-aircraft, or “Flak” towers to defend Berlin from enemy aircraft. Of these six, only three were built, and after the war they were “demilitarized” – or blown up, however the Flak tower in Humboldthain park in Gesundbrunnen was only partially destroyed.
Since April 2004 we have been leading groups through the interior of the tower. On this fascinating tour, visitors will be shown two of the seven floors of one of the biggest bunkers in the city. Here a dazzling underground landscape awaits – complete with dizzying views into the depths of the building. In addition, our guides present in-depth information about the history of the structure and the still on-going project to clean it up. To date, members of the Berlin Underworlds Association have spent a total of over 8,000 hours removing over 1,400 cubic metres of rubble – and have created in the process ideal sleeping quarters for bats. Therefore, so as not to disturb their hibernation and unnecessarily frighten our guests, we only offer this tour from April to the end of October.
For more detailed information about the Flak Tower, please take a look at Flakturm Humboldthain (in German language only).
