Bab al-Futuh is located in the Bab al-Futuh Square of Cairo. It is one of the oldest surviving gates in the city walls. Cairo’s famous al-Muizz Street starts from here and it goes all the way to Bab Zuweila. The Bab el-Futuh, or Gate of Conquest consists of a huge vaulted opening carved from a massive block of stone and flanked by two rounded towers. Bab al-Futuh was built by the powerful Fatimid vizier Badr al-Jamali in 1087. This gate of Cairo mark the beginning of stone masonry in Cairo and were built in the Fatimid era, a style borrowing from Byzantine architecture.
The gate entrance is covered with a shallow dome consisting of transition zones of four spherical-triangular pendentives. This is the first appearance of this type of dome in Islamic Egypt. The towers of Bab Al-Futuh are round and beautifully decorated, moreover they are dotted with arrow slits and openings for the pouring of boiling liquids on encroaching enemies. In past times, the great caravan of pilgrims returned each year from Mecca, entering this gate and making their way to the Citadel.
