Ehemaliger Flughafen Berlin-Tempelhof

You're standing at Tempelhof, Berlin's old airport. Take a look at that enormous building. Architect Ernst Sagebiel designed it in the Nazi era, as part of Albert Speer's plans to rebuild Berlin as Germania, the world capital Hitler had in mind. It became one of the largest buildings in Europe. British architect Norman Foster later called it the mother of all airports.
