Chefchaouen, or Chaouen, is a city located in the Rif Mountains in northwest Morocco. It is renowned for the remarkable buildings of varying shades of faded blue in its old town. Leather goods and weaving workshops line its steep cobbled paths. In the shaded central square of Outa el Hammam is the red-walled casbah, 15th-century fortress and keep with ethnographic and artistic exhibits. The octagonal minaret of the Great Mosque rises not far away.
