Built in 1565 by the Saadians, the Medersa (madrassa – Islamic school of learning) of Ben Youssef is the largest theological college in Morocco. The warrens of rooms (with student cells that once were home to 900 pupils) are clustered around small internal courtyards in typical Islamic architecture style, but the main internal courtyard is the real highlight here. The fine zellige tiling, stalactite ceilings, cedar-wood detailing, and Kufic inscriptions used as decoration across the courtyard’s interior make this medersa one of Morocco’s most beautiful buildings and a star medina attraction
