Just inside the Bab ech Chouhada, the restored Zaouia of Sidi Abid el-Ghariani dates from the 14th century and contains some fine woodcarving and stuccowork. The zaouia (complex surrounding the tomb of a saint) also houses the tomb of the Hafsid sultan Moulay Hassan who ruled from 1525 to 1543. There are no official opening hours, but you're most likely to find it open in the morning. Entry is with the multiple-site ticket.
