The university of Al Karaouine, founded in 859, is located in Fez. However, what attracts tourists most are the tanneries located in the Unesco-listed medina of Fes el-Bali. The traditional method of production is best viewed from the terraces of nearby shops. Despite the omnipresent stench, the view is fascinating. There are piles of raw hides piled up below, and tanners are bustling around huge vats.
