[3] This reduction dates from the time of the Alaouite sultan Sidi Muhammad ibn Abdallah (second half of 18th century), who made similar adjustments to the Bab Agnaou gate in Marrakesh.

[1] The decoration of the gate's outer façade includes three concentric semi-circles carved with polylobed and radiating motifs, which are in turn framed inside a rectangular alfiz.

The frame of the alfiz itself contains an Arabic inscription in Kufic script featuring a Qur'anic verse, translated as the following:[3] Be a community that calls for what is good, urges what is right, and forbids what is wrong: those who do this are the successful ones.

Do not be like those who, after they have been given clear revelation, split into factions and fall into disputes: a terrible punishment awaits such people.The gate's interior passage passes through four chambers and turns 90 degrees four times, constituting a complex bent entrance typical of Almohad military architecture.

[3] The inner façade of the gate, facing towards the city, is more simply decorated with a single polylobed semi-circle carved around the horseshoe archway, which is framed by a wide band filled with a sebka pattern.
