A lone visitor crosses the open courtyard of Al-Muayyad Mosque (Masjid Al-Muayyad Shaykh) in historic Islamic Cairo, walking beside the octagonal wooden-roofed ablution fountain (Mayda'a) supported by marble columns with intricate carved arches. In the background stands the mosque's distinctive ribbed dome decorated with a chevron stone pattern, flanked by the arcaded courtyard facade with pointed Mamluk arches. Built in 1420 CE by Sultan Al-Muayyad Shaykh, the mosque is located adjacent to Bab Zuweila (Bawabat Al-Mitwalli) and the Al-Khayamiya (tentmakers) bazaar in Old Cairo, and is considered one of the finest examples of Mamluk religious architecture in Egypt.
