The Mosque of Qani-Bay is a mosque in Cairo, Egypt. The complex is named after Qani-Bay al-Sayfi, nicknamed "al-Rammah", who was Grand Master of the Horse during the reign of Sultan al-Ghuri. It was built between AD 1503 and 1504 (AH 908) on a hill watching over the hippodrome and Mosque-Madrassa of Sultan Hassan. The site was chosen since the horse market and stables of the Citadel were originally located just off the square. Read more on Wikipedia
