M'zab Valley (UNESCO)

The M'zab Valley, inscribed as a UNESCO World Heritage Site in 1982, is a 20 km stretch of the northern Sahara containing five fortified cities built by the Ibadi Mozabite people between the 11th and 14th centuries. The valley is considered one of the most intact examples of traditional Islamic urban planning in the world.

Each of the five ksour — Ghardaia, Beni Isguen, Melika, Bou Noura, and El Atteuf — is built on the same pattern: houses arranged in concentric rings around a central mosque and minaret, with the market in the lower town and the residential area above. The design is both functional (maximum shade, minimum heat gain) and symbolic (the mosque visible from everywhere in the town). The Mozabite community has maintained this structure with virtually no external alteration for a thousand years.

A story
The M'zab Valley was settled by Ibadi Muslims after they were expelled from North Africa's main centres following their defeat in the Islamic civil wars of the 7th and 8th centuries. They chose the Sahara deliberately — a place isolated enough to preserve their minority sect from persecution. The five ksour they built were designed not just as shelter but as a complete civilisation: everything needed to maintain their faith and identity in an inhospitable place.
