It is located between the Taipei Metro Red Line and eastern shore of the Tamsui River, and between Civic Boulevard and the Sun Yat-sen Freeway.

Taipei's commercial center has since shifted southeast to Zhongzheng, Da'an and Xinyi, and Datong is far less important economically. Some of the last vestiges of Twatutia's commercial importance is preserved on Dihua Street. The old town of Daronpon is in the northern part of the district.
