Sections of the 10th-century Moorish defensive walls that once encircled the old town of Marbella, preserved in the streets around the historic centre. The most complete stretch runs along the northern edge of the casco antiguo, rising above a small garden. The walls are squat and thick, built of local rubble masonry, and give a clear sense of the original compact shape of the medieval town.
Worth a few minutes' detour from the Plaza de los Naranjos. Look for the Torre del Moro, a surviving watch tower, and the gate opening that once marked the main entrance from the north. Free to view from the street at all times.
