Sinan Erdem Dome

The Sinan Erdem Dome (Turkish: Sinan Erdem Olimpik Spor Salonu), formerly known as the Ataköy Dome, is a multi-purpose indoor arena that is located on the European side of Istanbul, Turkey.

It has a seating capacity of 22,500 for concerts and for the sport of basketball it has a seating capacity of 16,000 people, making it Turkey's largest multi-purpose indoor venue and the third largest in Europe (although it is not the third largest in Europe in capacity for basketball use). The arena is named after Sinan Erdem (1927–2003), who was the President of the National Olympic Committee of Turkey from 1989 until his death in 2003.
