This is Kongresshalle at the Nazi Party Rally Grounds in Nuremberg, Germany. Construction on this massive congressional hall for Hitler's National Socialists started in 1935 but was halted before completion due to the outbreak of WWII. About twice the size of Rome's Coliseum, it is the largest surviving monument of Nazi architecture in Germany. And its continued renovation by the city has sparked controversy. #Germany #history #wwii #travel
