Dortmund’s famous and massively popular and succesful Bundesliga soccer team plays its home games at the legendary Westfalenstadion, now branded as Signal Iduna Park. Cheering on the team with fans clad in the club's signature bumblebee-yellow and black can be a transporting experience.
Guided tours (in German, adult/concession €15/10) of the 80,000-seat stadium, Germany's largest, are popular. Check timings and book tickets online.
