Hitler’s forgotten attempt to build the world’s largest Olympic stadium

On September 7, 1937, German construction workers laid the cornerstone for what was to become the world's largest stadium — one that would hold over 400,000 spectators. Designed by Hitler's close adviser Albert Speer, the monumental structure drew as much inspiration from the Greek Panathenaic Stadium of Athens as it did from Hitler's brazen megalomania. But in the end, it was simply not meant to be, a project cut short by the demands of World War II and the eventual demise of the Third Reich.
