The open courtyard (sahn) of Sultan Al-Muayyad Mosque in Old Cairo, showing the octagonal wooden ablution kiosk (mida'a) at center, flanked by pointed Mamluk arches along the arcade (riwaq), and the mosque's distinctive chevron-carved stone dome in the background. A single man walks across the sun-lit courtyard while pigeons rest on the sandy ground. Sultan Al-Muayyad Mosque was commissioned by Mamluk Sultan Al-Muayyad Shaykh and completed in 1420 CE, and is considered one of the finest examples of late Mamluk religious architecture in Egypt, situated adjacent to Bab Zuweila (Bab El-Mitwalli), one of the last surviving gates of Fatimid Cairo.
