Ksar Ouled Soltane
One of the most striking archtectural achievement in Northern Africa are the “Ksour” (plural of “Ksar”), fortified Berber strongholds consisting of many rooms called “ghorfas” used for storing grain.
The structures look so outlandish and bizarre that Geaorge Lucas used them as the backdrop for his planet Tataouine (actually a small city in Tunisia) in star Wars, home of Anakin Skywalker.
