Madrassah ben Youssef The Madrassah ben Youssef is one of the most interesting monuments of the city. Built in 1570 by Saadi, restored in 1960, the Koranic school is the largest in the Maghreb. It could accommodate up to 900 students enrolled in only 132 cells! Unusually, the rooms … upstairs have windows overlooking seven small “courtyards” home. Moreover, unlike the Arab-Andalusian architectural tradition, some of its opening overlooking the medina. The decor is much more conventional and we will not fail to admire the sculptures in cedar, stucco and zelliges that adorn the monument.
