Ksar or qá¹£ar (), in plural ksour or qsour (), is a type of fortified village in North Africa, usually found in the regions predominantly or traditionally inhabited by Berbers (Amazigh). The equivalent Berber term used is ' (singular) or (plural).
The Arabic qaá¹£r (), frequently pronounced in the Maghreb, was probably borrowed from the Latin word .
Ksour or igherman are widespread among the oasis populations of North Africa, found in Tunisia, Algeria, and Libya, and are also found on the Djado Plateau and in the commune of Fachi in Niger. They are sometimes situated in mountain locations to make defense easier; they often are entirely within a single, continuous wall.
Ksour in the Maghreb typically consist of attached houses, often having a fortified communal granary like those in Algeria, or the ghorfa and agadir types known in Tunisia and Morocco respectively, beside other structures like a mosque, hammam, oven, and shops.
The building material of the entire structure usually is adobe, or cut stone, desert salt and adobe. The idea of the ksar as a granary is a confused notion of two things: the granary itself, found within a ksar, and the ksar, a village, typically with granaries within it. Ksars form one of the main manifestations of Berber architecture.
