Ali Ben Youssef Medersa (Madrasa)
The Ben Youssef Madrasa was an Islamic college in Marrakech and was named after the amoravid sultan Ali ibn Yusuf (reigned 1106–1142), who expanded the city and its influence considerably.
The college was founded during the period of the Marinid (14th century) by the Marinid sultan Abu al-Hassan and allied to the neighbouring Ben Youssef Mosque.
The building of the madrasa, as it is now, was (re-)constructed by the Saadian Sultan Abdallah al-Ghalib (1557–1574).
It is the largest Medrasa in all of Morocco.
In 1565 the works ordered by Abdallah al-Ghalib were finished, as confirmed by the inscription in the prayer room.
