Ghardaïa (Arabic: غرداية, Tumzabt: Taɣerdayt) is the capital city of Ghardaïa Province, Algeria. The commune of Ghardaïa has a population of 93,423 according to the 2008 census, up from 87,599 in 1998, with an annual growth rate of 0.7%.
It is located in northern-central Algeria in the Sahara and lies along the left bank of the Wadi Mzab. The M'zab in the Ghardaïa Province was made a World Heritage Site in 1982, as a cultural property evaluated under the criteria II (for its settlement affecting urban planning even to the present century), III (for its Ibadi cultural values), and V (a settlement culture which has prevailed to the present century). Ghardaïa is part of a pentapolis, a hilltop city amongst four others, built almost a thousand years ago in the M’Zab valley. It was founded by the Mozabites, an Ibadi sect of the Berber Muslims.
It is a major centre of date production and the manufacture of rugs and cloths. Divided into three walled sectors, it is a fortified town. At the centre is the historical Mʾzabite area, with a pyramid-style mosque and an arcaded square. Distinctive white, pink, and red houses, made of sand, clay and gypsum, rise in terraces and arcades.
