4-Story Granaries Built of Mud in Tunisia

"The Ksar Ouled Soltane is a popular tourist attraction in Tunisia’s southern province of Tataouine. The Ksar Ouled Soltane is a particularly attractive and well-preserved fortified granary built by the Berbers in the 15th Century. A Ksar is a term describing a Berber village consisting of generally attached houses, often having collective granaries and other structures (mosque, bath, oven, shops) widespread among the oasis populations of North Africa.
The multi-level granaries are called ghorfas and the fortified village is the Ksar. Granaries were fortified to stop raids on a village’s food supply. Ksar Ouled Soltane is located on a hilltop, to help protect it from raiding parties in previous centuries. You can explore all the little staircases and different levels of the structure.…"http://www.zacktravel.com/ksar-ouled-soltane/
