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.
