The Jami al-Jadid (New Mosque) is one of three mosques built by Sultan al-Nasir Muhammad (r. 1310-1341). Of those three, only the
Masjid al-Sultan al-Nasir Muhammad ibn Qalawun at the Citadel remains extant; this mosque, located north of Fustat, and another near the shrine of Sayyid Nafisa have not survived. This jami was constructed between 1311-1312 (711-712 AH) on the shore of the Nile at the northern limits of Fustat. Reconstructed drawings show a cross-axial plan with a riwaq, and a dome in front of the mihrab, a plan which influenced several later mosques in Cairo.
