Al-Rifa’i Mosque is one of Cairo’s largest mosques. It took 43 years to build this beautiful sanctuary that combines different Islamic architectural styles. Located in “Midan Al-Qalaa” or the Citadel Square, it faces the Mosque-Madrassa of Sultan Hassan which it rivals in size and grandeur. This Mosque is the resting place of many members of the Egyptian Royal Family, including the last king, King Farouk. The last Shah of Iran has also been buried in this mosque in 1980. Make sure you notice the ornamental window grills and the breathtakingly high ceiling, held up by 44 colossal pillars.
