Fes or Fez (Arabic فـاس [Fās], French Fès) is the third largest city in Morocco, after Casablanca and Rabat, with a population of 946,815 (2004 census). It is one of the four so-called "imperial cities" (the others are Marrakesh, Meknes and Rabat). Fes is separated into three parts, Fes-al-Bali (the old, walled city), Fes-Djedid (new Fes, home of the Mellah), and the Ville Nouvelle (the French-created, newest section of Fes). The Medina of Fes-al-Bali, the larger of the two medinas of Fes, is believed to be the largest contiguous car-free area in the world.
