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

The top and bottom chords are made up of circular hollow sections, which form a triangular shape.

There are three main trusses and secondary circular girders that rest on them, which builds up the skeleton structure, while trapezoidal steel sheet covers complete the roofing system.
