The new 17,000-seat O2 World Arena in Berlin-Friedrichshain is to open on 12 September with a concert by American heavy metal band Metallica. Constructed by the US American Anschutz Group near the Ostbahnhof and the East Side Gallery, the high-tech multi-purpose arena can be transformed from a concert hall to a sports stadium within a few hours. It will be home to the ice hockey team Berliner Eisbaeren and the Alba Berlin basketball team.

The proceeds from the Metallica concert will go to local charities.
