Olympic Village -- 1936 Summer Games; Berlin, Germany
Home to more than 3,800 athletes (including Jesse Owens) during the infamous Nazi Games of 1936, the former village in Elstal was used as a military hospital during WWII, and housed Soviet troops until it was abandoned after the fall of Communism. While Owen's room has been completely restored, the rest of the complex is only now getting a gradual, well-needed facelift. For a fascinating look around, click here.
Olympic trivia: Known as the Games where Jesse Owens won four track and field Golds in front of Adolf Hitler, few people remember that baseball Hall-of-Famer Jackie Robinson's brother, Mack, actually took home Silver in the 200 meter.
