11. Citadel Of Saladin
One of the many places in ancient Egypt to be declared UNESCO World Heritage Sites, the citadel was built by the famous Ayyubid ruler Saladin to protect the Cairo and Fustat (the first Egyptian capital under the Caliphate) against Crusaders. The huge fortification is lined by several watchtowers and houses several stunning mosques and the Well of Joseph inside. The Al-Naseer, Sulayman Pasha and the Al Gawhara Palace museum are three places that are a must for Egypt sightseeing tours in Cairo.
