Ksar Ouled Soltane (Arabic: قصر أولاد سلطان ) is a fortified granary, or ksar, located in the Tataouine district in southern Tunisia. The ksar is spread out over two courtyards, each of which has a perimeter of multi-story vaulted granary cellars, or ghorfas. Like other ksour (plural of ksar) created by North African Berber communities, Ksar Ouled Soltane is located on a hilltop, to help protect it from raiding parties in previous centuries.
Ksar Ouled Soltane is now a tourist destination, with visitors coming to see its well-preserved granary vaults. It was also featured in the film Star Wars: The Phantom Menace in some of the scenes used to represented the slave quarters of Mos Espa, where the character Anakin Skywalker lived as a boy.
