what happened to the round city of baghdad
Round city of Baghdad None of the structures of the city has survived, and information are based on literary sources. The caliphal palace and the main mosque were located inside the circle. Influenced by the apadana design of ancient Iranian architecture, the mosque was built with a hypostyle prayer-hall with wooden columns supporting its flat roof. The caliphal palace featured an iwan and a dome-chamber immediately behind it, resembling Sasanian palace design (such as that of Gor and Sarvestan). Building materials was mostly brick (sometimes strengthened by reeds), reflecting Mesopotamian architecture.[7]
