Formerly known as the Westfalenstadion, the home of Borussia Dortmund is the largest stadium in Germany.
Dortmund's impressive form over the past four years, which has seen them win back-to-back Bundesliga titles and contest the Champions League final, has increased their popularity throughout Europe.
Signal Iduna Park is often one of the must-see stadiums on any football fan's list, more so because of Die Gelbe Wand—or The Yellow Wall. Dortmund's south stand is Europe's largest free-standing grandstand in Europe with 24,454 filling it each and every home game.
