The Royal Walls of Ceuta (Murallas Reales de Ceuta) are a system of coastal defence in Ceuta, an autonomous Spanish city in north Africa. On 3 July 1985 they were declared a Spanish heritage site. The walls were one of 100 candidates for the 12 Treasures of Spain in 2007, and the only one of those in Ceuta.
