The formation, like the fortress of Tasghîmût near Marrakesh, is strategically located and naturally forms an almost complete fortress. Gara Medouar has only one large opening, a ravine in the south; about one third of the mountain's perimeter has been fortified by walls, the most important of which is the wall going straight across the ravine in the south. This well-preserved wall (the "low wall") is 8 m (26 ft) high where it abuts the rocks, and in places rises to 12 m (39 ft); it is 80 m (260 ft) long and about 4 m (13 ft) thick, and consists of limestone blocks held together with lime mortar.[1]
