Spodek (saucer in Polish) is a multipurpose arena complex in Katowice, Poland, opened in 1971
Aside from the main dome, the complex includes a gym, an ice rink, a hotel and three large car parks. It is the largest indoor venue of its kind in Poland. It hosts many important cultural and business events. Music concerts are especially common non-sport events. Spodek can hold 11,500 people, although this number is in practice limited to 10,000 or even 8,000 due to stage set-ups obscuring the view. Its name is "saucer" in Polish as it resembles a tilted flying saucer.

From Joey -
Soundcheck in the saucer and today’s curveball, a press junket from Warsaw has shown up and LC has given them a very rare go-ahead to hangout and shoot a little of the soundcheck. Warsaw count yourself lucky as this kind of thing happens never.
