Spodek is a multipurpose arena complex in Katowice, Poland, opened on 9 May 1971. Aside from the main dome, the complex includes a gym, an ice rink, a hotel and three large car parks. It was the largest indoor venue of its kind in Poland until it was surpassed by Tauron Arena in 2014. The Spodek hosts many important cultural and business events. Music concerts are especially common non-sport events.
