Hm, will ask here. don't ask me how I've come to this.

As far as I know, in 20 century Berlin had 2 red light districts - Kurfürstenstrasse in the West and Oranienburger Strasse in the East. The Oranienburger Strasse has been disbandled by the police this year, on Kurfürstenstrasse there was nothing also earlier. When have it been disbandled, +-?

 

Judging on the architecture, trhere have been a dozens of strip bars, porn cinemas and other degeneracies yearlier, in 70s or 90s.
