The Zawiya of Moulay Idris II honours the founder of Fes, whose tomb has made it one of the holiest pilgrimage sites in Morocco, historically so sacred that non-Muslims and even beasts of burden were once barred from the surrounding streets. Its green-tiled shrine sits at the very heart of Fes El Bali, the spiritual centre of the old medina.
