One of the most prominent landmarks in the southern part of Ben Youssef Square in the old city is the dome of the Almoravid. This dome is unique in its shape and takes in the shape of the rectangle. In its external façade there are exquisite engravings representing shapes and arches forming a seventh star adorning its entrance. The top of this dome shows us the name of Sultan Ali bin Yusuf as revealed to us by some researchers.
