Chefchaouen, or Chaouen, is a city located in the Rif mountains, north-west of Morocco. It is famous for the remarkable buildings of different tones of faded blue of its old town. Leather and weaving workshops line its steep cobbled alleys. In the shaded central square of Outa el Hammam is the casbah with red walls, fortress and dungeon of the fifteenth century with ethnographic and artistic exhibitions. The octagonal minaret of the Great Mosque rises not far from there.
