The West Berlin building, the subject of the video is a complete abomination inside and out. It's a flat version of the Bonaventure hotel without that building's attractive exterior.

What's funny is that the East Berlin counterpart, built first and shown in the video, is actually a lovely example of modernism and the international style, both new at the time. So that was demolished and we get the Brutalist, abandoned thing in West Berlin instead.

In my mind it's the most beautiful building in Germany. Change my mind. ;)

I knew for years that this building exists, at least by name, but nothing prepared me when I visited and event at the neighboring fairground in 2018 turning a corner and suddenly see this spaceship hulking in the fog.
