Al-Rifa'i Mosque (Arabic: مسجد الرفاعى‎, transliterated also as Al-Rifai, Al-Refai, Al-Refa'i, and named in English the Royal Mosque), is located in Cairo, Egypt, in Midan al-Qal'a, adjacent to the Cairo Citadel. The building is located opposite the Mosque-Madrassa of Sultan Hassan, which dates from around 1361, and was architecturally conceived as a complement to the older structure. This was part of a vast campaign by the 19th century rulers of Egypt to both associate themselves with the perceived glory of earlier periods in Egypt's Islamic history and modernize the city. The mosque was constructed next to two large public squares and off of several European style boulevards constructed around the same time.
