Ksar Ouled Soltane (Arabic: كصر أولد سلطان) is a fortified granary, or ksar, located 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 created by North African Berber communities, Ksar Ouled Soltane is located on a hilltop, to help protect it from raiding parties in previous centuries.
