With an impressive capacity of over 81,000, Signal Iduna Park is home to Borussia Dortmund. It was first opened in 1974, so it could play host to games in the 1974 World Cup. Before changing its name in 2005, it was known as Westfalenstadion. At the time, the stadium was seen as a trendsetter because, generally, stadiums were bowl-shaped, whereas it had a rectangular shape. The fact that it had four separate stands was the basis for many other modern stadiums, like Glasgow Rangers FC’s Ibrox Stadium. The venue hosted three matches in the first round of the World Cup and then a second-round group match between Brazil and Holland. The only further changes happened when Dortmund grew in prominence in the 90s.

Situated in the city's south, close to the conference centre, the central rail station is just 3kn away. It can also be reached easily by car using either the B54 or B1.
