The Great Mosque is located in the northern section of the city's heart. Its plan is rectangle (108m x 92m) with 1.7m thick mud brick walls fortified with semi-circular towers at the corners. All that remains today are the baked brick minaret and prayer hall (haram) façade with eleven arches that were added by Nur al-Din al-Zanki during the 1165 renovation of the mosque.
