Stade panathénaïque
Along with his plans for the "Welthauptstadt Germania" ("world capital Germania"), Albert Speer made the plans for the world's largest stadium which was to be located on the rally grounds. Derived from the Panathenaic Stadium of Athens, it would have offered 400,000 seats in a horseshoe shape; planned dimensions: length: 800 m, width: 450 m, height: 100 m, building area 350,000 m².
