Today, we visited what is said to be one of the hardest to visit landmarks in Berlin: the Hochbunker Pallasstrasse in Schöneberg. Apparently, there is only one guided tour a year, so we’ve been quite lucky!
The bunker was built from 1943 by prisoners of war, many of them from the Soviet Union. It was meant to serve as a bunker for the neighboring phone and telex central. The communications central was of great importance during the war, as it connected the different offices of the German authorities. The bunker was not finished, though, and the phones and telex machines never moved in.
Contrary to what happened to most other military installations after the war, the bunker in Pallasstrasse was not blown up (there were a couple of attempts at it, though). The danger of damages in the neighborhood was considered too high.
In the 1980s the bunker was upgraded to a civilian air-raid shelter, with a capacity of almost 5000 people, hence making it the biggest air-raid shelter in Berlin. Only a few years ago, the bunker was turned into a memorial.
