The location, part of the Muqattam hill near the center of Cairo, was once famous for its fresh breeze and grand views of the city, and was fortified by the Ayyubid ruler Salah al-Din (Saladin) between 1176 and 1183 AD, to protect it from the Crusaders. Only a few years after defeating the Fatimid Caliphate, Saladin set out to build a wall that would surround both Cairo and Fustat. Saladin is recorded as saying, "With a wall I will make the two into a unique whole, so that one army may defend them both; and I believe it good to encircle them with a single wall from the bank of the Nile to the bank of the Nile."
