O2 World is a multi-use venue in Berlin, Germany, opened in September 2008. With a capacity of 17,000 people, home of the hockey team and Eisbären Berlin basketaball team ALBA Berlin, and features games like ice hockey, basketball and handball, as well as concerts. I liked it because this stadium had a grass enclosure, a striking color that caught my attention! The Berlin Bear! What's more, it's directly opposite the Berlin Wall!
