Fortifications of Fez are a group of gates, defensive walls, kasbahs, and ramparts that surround Fes el-Bali and Fes el-Jdid in the city of Fes, Morocco. These fortifications were built and expanded through several historical eras, from the rule of the Idrisids, Almoravid, Almohads, Marinids and Saadians all the way to the Alaouite era. The fortifications include a group of historical main gates, the most important of which are Bab Ftouh, Bab Mahrouk, and Bab Guissa. The Fortifications of Fez were inscribed as a UNESCO World Heritage Site in 1981 as part of Medina of Fez.
