Tétouan's medina is ringed by roughly 5km of fortified walls and entered through seven historic gates, among them Bab Tut, pictured here opening onto one of the medina's covered souks. Rebuilt in the 15th century by Andalusian refugees expelled from Spain, the old town's layout, tilework, and whitewashed houses reflect a distinctly Andalusian character that UNESCO recognized as the most intact of Morocco's historic medinas when it inscribed the site as a World Heritage property in 1997. Inside, narrow lanes lead past specialized souks — leather, wool, jewellery — largely unchanged for centuries.
