M’Zab Valley is the Algerian UNESCO site famous for historic fortified settlements and distinctive Saharan architecture.
The valley lies in northern Algeria’s Sahara and contains five principal fortified towns, known collectively as the pentapolis. These settlements were established by Ibadi Muslims, beginning with El Atteuf in the 11th century. Their compact layouts, defensive walls, and simple geometric buildings were adapted to a harsh desert setting.
Ghardaïa is the best-known town in the valley and serves as its main urban center. Beni Isguen, Melika, Bou Noura, and El Atteuf are the other principal settlements. The towns’ organization reflects both religious traditions and the practical need to manage scarce water and protect communities.
The M’Zab Valley is sometimes confused with Morocco’s Draa Valley, another important North African oasis region. UNESCO inscribed the M’Zab Valley in 1982 because of its unusually well-preserved cultural landscape and architecture.
