The remains of the so-called “Fuehrerbunker” are situated beneath a parking-lot at the corner of 'Gertraud-Kolmar-Strasse' and 'In den Ministergaerten', marked by an information panel that our association provided. During the Cold War, the site was next to the Berlin Wall, the border area between East and West Berlin. In 1988, some pioneers of the East German National Army excavated the bunker and filled it in. Today there are just a few fragments of the floor and parts of the walls in the soil but no hollow spaces whatsoever. It is absolutely not possible to visit the “Fuehrerbunker” – no chance!
