This medersa, built between 1350 and 1357, is the biggest in Fez. Pass through the magnificent entrance with its heavy copper work doors, and then be impressed by the abundance of earthenware, the refinement of the sculptured wood and plaster and the chiseled stalactites called mukarnas, the hallmark of Merenid architecture. A canopy of typical Fez green tiles surmounts the onyx and marble courtyard.
