The Abbasid Palace is the only remaining Abbasid palace in Baghdad and is located near the northern gate overlooking the Tigris River. It is believed that the Caliph Al-Naser Lidinillah (Al-Naser Ledinillah) built it between 1179 AD - 1225 AD. The palace was distinguished by a distinctive architectural design, as it contains a central courtyard and two floors of rooms, with beautiful arches and muqarnas in brick, and an impressive iwan with brick ceiling and facades.
