One of the oldest market places this souk, off Talaa Kebira, has graceful plane trees shading the stalls selling ceramics and traditional cosmetics, including henna. The mohtassib (price-controller), now defunct, had his office here and you can still see his large scales. On one side is the restored Maristane Sidi Frej, a former psychiatric hospital built by the Merinids in the 13th century. Leo Africanus worked here as a young man. It's now a small kissaria (covered market).
