Ksar

The ksar (plural ksour) is the largest and most communal of the earthen building forms across the Saharan-Maghreb region. Where a kasbah is a single seat of authority, a ksar is an entire fortified village: a collective settlement enclosed within shared defensive walls, organised around a mosque, a public square, granaries, and a dense weave of attached dwellings.

The term derives from the Arabic qasr, itself probably borrowed from the Latin castrum. The Tamazight equivalent is igherm (plural igherman), used across Morocco and parts of Algeria. Both terms designate the same kind of structure with the same social function: collective defence against raids, communal storage of grain and goods, and the spatial organisation of a settled or semi-settled community in a marginal environment.

The geographic distribution is broad. Ksour are found across southern Morocco, the M'zab Valley and Saharan oases of Algeria, the Tataouine region of southern Tunisia, the Nafusa mountains of Libya, the Adrar plateau of Mauritania, and as far south as the trans-Saharan trade towns of Mali and Niger. The four Mauritanian ksour of Ouadane, Chinguetti, Tichitt, and Oualata, founded in the eleventh and twelfth centuries to serve the Saharan caravans, are inscribed together as a single UNESCO World Heritage Site.

Construction is almost entirely earthen. Pisé walls, adobe partitions, palm-wood roofs covered with cane and compacted earth. The materials are local; the structural intelligence is local; the labour was organised through traditional collective arrangements involving the jma'a (village assembly) and the maalem (master mason).

Ksour have suffered the same attrition as kasbahs but on a wider scale. Three quarters of Morocco's ksour are estimated to be in significant disrepair. UNESCO inscriptions and Getty-led conservation programmes have stabilised a small number of significant examples; the broader landscape remains vulnerable.
