This petite mosque, the oldest in Egypt with a stone facade, was built in 1125 by one of the last Fatimid caliphs. Several features appear here that became part of the mosque builders’ essential vocabulary, including muqarna (decorative stalactite-type stone carvings) vaulting and the ribbing in the hooded arch. If you climb to the roof, you’ll have a great view along the Bein Al Qasreen section of Sharia Al Muizz Li Din Allah.
