Fez is one of the best sights in the world. It is famous for its ancient walled city, often compared to the walled city of Jerusalem. The whole old city of Fez has been declared a UNESCO World Heritage site. The immense medina of Fes-l-Bali (the old city) is a huge labyrinth. Lose yourself in the hustle and bustle of the various markets, and find your way out once you have had enough of all the sights, sounds, and smells that will overwhelm your senses. You should at least try to find the Medersa Attarine, the Medersa Cherratine and Medersa Seffarine, three stunning old buildings near the center of the maze. The other thing you shouldn't miss is the people at work in the median: coppersmith, tanners, and dyers. The view from the hills surrounding the old city is breathtaking - there are two fortresses overlooking the old city, the Borj Nord which contains an armaments museum, and the Borj Sud, which is being developed for tourism.
