Fez is enthralling tradition In its heyday, Fez attracted scholars and philosophers, mathematicians and lawyers, astronomers and theologians. Craftsmen built them houses and palaces, kings endowed mosques and medersas (religious schools), and merchants offered exotic wares from the silk roads and sub-Saharan trade routes. Fes is a city whose cultural and spiritual lineage beguiles visitors. Something of the medieval remains in the world’s largest car-free urban area: donkeys cart goods down the warren of alleyways.
