Admission Resize text Once the thriving capital of the Abbasid Caliphate, Samarra in the 9th century served as the center of an Islamic empire that stretched from northern Africa to Central Asia. Its striking spiral minaret serves as an enduring reminder of the Great Mosque that once enclosed this sacred ground along the banks of the Tigris River. Historian Justin M. Jacobs focuses on Samarra’s rare preservation of Islamic art, architecture, and city plans from the heyday of the Abbasid Caliphate.
