Bab El Futuh

This gate is like Bab El Nasr consists of two great towers solid for two thirds of their height, defending a great archway which is set back between them.
The passage way behind this arch, however instead of being roofed by an interesting vault, is covered by a dome of stone voussoris resting on a spherical triangle pendentives of the same curvature. Moreover, the towers themselves are oblong with rounded fronts and are not divided externally into storeys.
The whole measures 22.85 m in width, 25.22 m in depth and 22.33 m in height from the original ground level to the top of the crenellations.
The platform over the shallow dome is reached by a staircase which runs up alongside the inner face of the curtain wall to the east of the gateway. The towers are 7.58 m width, the straight sides measured to the edge of the rounded front, which is formed by a segment of a circle only, instead of being semicircular in plan is 9.26 m.
The courses of masonry average 52 m in height the stretchers from 80 cm to 1.3 m in length and the headers from 23 to 70 cm. In the sixth course from the present ground level we observe a row of stone circles about 45 m in a part running around the tower, they are as we have seen the ends of columns.
The lower solid part of each tower is decorated with three great arched panels one on each side and one on the front, the latter being curved in a plan and higher than the other two.
The panels on the outer sides and front of each tower are perfectly plain and without any moulding, but on the side of each tower next the gateway is decorated with an inner ring of cushion voussoris.
The upper part of each tower is perfectly plain on the outer sides, the smooth surface being broken by a single arrow-slit. The front faces, however are each pierced by three arrow-slit each set in a shallow recess with a semicircular arched head, the whole being surrounded by a large rectangular molded frame.
The gateway; A great splayed semicircular arch is set back 7.7 m between the towers. A rectangular lattice work of slightly.
