OT... this is a copy of an earlier post but with the pics now hosted away from all my other pics.
This shelter is built below the Gesundbrunnen station of BVG (Berlin metro) for use during World War 2. It is now the HQ of the Berlin Unterwelten Association (website here) and, as well as allowing tours through the bunker, they exhibit relics dug up from other Berlin WW2 sites.
The way in (from a discrete door in the U-Bahn station)
Passageway
Some of the exhibits
An enigma machine recovered from the rubble of a Nazi government building
So not only has Berlin got its own underground association, they are well regarded by the city, caretake a number of sites around Berlin and are often called in when new sites are found.
