The Mosque-Madrassa of Sultan Hassan is a gigantic Mamluk era mosque and madrassa located near the Citadel in Cairo. Its construction began 757AH/1356 CE. It took three years to complete the work without even a single day of idleness. The mosque was considered remarkable for its fantastic size and innovative architectural components at the time of construction. Al-Maqrizi, who commissioned it, was a sultan of a short and considerably unimpressive profile, noted that within the mosque were several "wonders of construction”. The mosque was, for example, designed to include schools namely Shafi'i, Hanafi, Maliki and Hanbali.
