Signal Iduna Park

Signal Iduna Park, officially known as Westfalenstadion, is a multi-purpose stadium located in Dortmund, Germany. It is primarily used for association football matches, hosting the home games of Borussia Dortmund, the club that owns the stadium.

The stadium was inaugurated on 2 April 1974 with a Bundesliga match between Borussia Dortmund and Werder Bremen. It replaced the former Stadion Rote Erde, which had a seating capacity of 42,000. The current capacity of Signal Iduna Park is 81,365 for league matches and 66,099 for international matches, making it the largest football stadium in Germany. The stadium's design was the work of architect Planungsgruppe Drahtler, and its construction cost was approximately €200 million.

As a UEFA category four stadium and one of the largest stadiums by capacity in Europe, Signal Iduna Park has been the venue for several notable football events. It hosted matches during the 2006 FIFA World Cup, including a semi-final, and it has also hosted the UEFA Cup final in 2001 and the UEFA Champions League final in 2013. In 2009, The Times newspaper listed it as the best football stadium in the world, largely due to its renowned 'Yellow Wall', which is the largest free-standing grandstand in Europe with a capacity of 25,000. By its 45th anniversary, Signal Iduna Park had welcomed more than 50 million spectators. The stadium is expected to be one of the potential venues for future international football events.
