In the 1960’s, Borussia Dortmund’s old home stadium Rote Erde was pretty much falling apart. They therefore started to draft plans for a new stadium. It wasn’t until 1974, ahead of the World Championship, however, that the plans bore fruit. The stadium was inaugurated in April 2nd 1974 with a game between Dortmund and Schalke 04, which is one of the hottest rivalries in German football.
During the 1990’s Dortmund had great triumphs in both Bundesliga and in the European cups. Thanks to this, there was a need for increasing the spectator capacity. After expansions in 1999, the stadium could hold 68,600 fans. With the latest expansions in 2004, the current capacity was reached.
During the 2006 Football World Championship in Germany, Signal Iduna Park was one of the most used stadiums. Among other games, the semi-final between Germany and Italy was played here – a game that the Italians won.
