Fes: Why go
The oldest imperial city in Morocco, Fès (or Fez) is the spiritual core of this country. It is home to some of north Africa's finest mosques and medersas (Islamic schools), and its largest intact medina - 10,000 labyrinthine alleys lined with leather and carpet stalls, apothecaries and barbers, spice merchants and grocers, tinkers and tailors, all jostling with tourists and a very healthy contingent of locals. It's a gritty city and the only transport is mules and trolleys, so you'll be dodging mule dung and impatient porters, all while the whiff of tanneries and street butchers fill the air. All in all, it's more evocative, authentic and medieval than Marrakech, as well as tougher to penetrate. Expect to get lost several times walking to/from your hotel. It's all part of the fun.
The city is divided into 3 main sections: Fès el-Bali (old Fes), the amazing, almost bewildering array of alleyways in the walled medina, Fès el-Jdid, home to the Royal Palace and Jewish quarter, and the Ville Nouvelle, the smart modern administrative district in the southwest.
