The History of the Sinan Erdem Dome

World finals under one roof

The dome opened in 2010, in time for the FIBA World Championship, and the tournament's final was played here. Later, it hosted EuroLeague Final Fours, among them those of 2012 and 2017. Besides basketball, volleyball comes here too: in 2026, the women's EuroVolley finals took place in the hall. Concerts and shows also fill the rest of the calendar. For the European Games of June 16–27, 2027, Istanbul builds no new venues and uses existing ones such as this dome.
