This is a video (Color! 8.25) from the NAZI ERA showing Berlin prior to WWII, with the old architecture intact. It's a documentary for the 1936 Olympic Games, but it simply shows the ordinary life in the city. In the second half the early stages of the construction of Germania can be seen, together with the New Reich Chancellery and the SS. No Führer, sorry, but there are SWASTIKAS.

PPS: Roughly the 1st minute only has the Victory Column (after it was moved), so you maybe want to skip that part.
