Also known as Westfalenstadion, this German landmark hosted World Cup games in both 1974 and 2006, and is known for one of the last remaining standing-room-only terraces in a soccer stadium. The Südtribüne holds 24,454 of the wildest fans in the world decked out in Borussia Dortmund colors and is appropriately nicknamed the "Yellow Wall."
