Berlin
Hitler's bunker, now a parking lot.
"The Führerbunker (German, literally meaning "shelter for the leader" or "the Führer's shelter") is a common name for a complex of subterranean rooms in Berlin, Germany, where German dictator Adolf Hitler and his wife Eva Braun committed suicide during World War II. The bunker is perhaps the most famous of Hitler's Führer Headquarters; another famous one is the Wolf's Lair (Wolfsschanze) in East Prussia." – Wikipedia
