Beneath the surface there is a whole dark world in Berlin waiting to be revealed. It contains large dark bunkers from the war days, subterranean underground channels, hidden tunnels that lead to rooms that have been forgotten somewhere in difficult times - in short, a Berlin that is not talked about today. Not talked about, unless you arrive to the Berliner Unterwalthen, the museum that stores the dark and mysterious parts of Berlin's not-simple history.
The purpose of the Berliner Unterwalten is to study the forgotten places hidden in Berlin. The organization, whose name translates to "underground worlds of Berlin," finances these activities through guided tours it organizes at these sites, at low costs.
You can find yourself hearing explanations and being guided into places you would have never reached alone, such as your visit to a tower that contained anti-aircraft weapons and was partially destroyed during World War II. You can enter a huge underground bunker from the days Hitler ordered the destruction of Germany, trying to ensure that nothing would be left to the occupiers. Some difficult thoughts might come up to you when you visit a metro station that contains an atomic bomb bunker for emergencies, a remnant of the Cold War days. And you may even wander through a network of shelters that were used to defend against air raids during the difficult days of Berlin during World War II.
The tours at the museum and the sites are in English, German and several other languages, but not in Hebrew.
Ticket price plus guidance is 9 euros, and 7 euros for students, and seniors.
Take the U8 line to the southern exit of the Gesundbrunnen underground station. The exit signs will direct you to Humbulthein Park and Brunnenstrasse.
