Loosely translated: “World High City” Germania. IIRC, this was the city that “Hitler’s Architect” Albert Speer designed. That dome in the top of the picture was supposedly several hundred feet high.
This likely what Berlin might have become if the Nazis won WW2.
World Capital City, actually...
Speer's father, a successful architect, took one look at that model and said, "You people must be crazy." (He also went into convulsions of disgust when introduced to der Fuehrer.)
Hitler himself, seemed aware of the fact that an artificially created capitol would be a sterile aesthetic failure.
