M'Zab Valley
UNESCO World Heritage Site: M'Zab Valley (1982). Five Fortified Mozabite Hill Towns Built From The Eleventh Century Around A Shared Mosque Topped Hill Plan, Widely Studied As A Model Of Vernacular Desert Urbanism; Le Corbusier And Other Modernist Architects Cited Ghardaia'S Geometry Directly · Ghardaia, Ghardaia
Five fortified hill towns rise above a dry wadi in the northern Sahara, each built around the same idea: a mosque at the summit, houses stacked concentrically down the slope, and narrow covered streets that keep the heat out better than almost any other desert architecture anywhere. Ghardaia is the largest and the one most visitors see first, its market square and old quarter climbing toward the Sidi Aissa mosque, but the valley's four other towns - Beni Isguen, Melika, Bou Noura and El Atteuf - each keep their own version of the same plan, and Beni Isguen in particular guards its own customs closely and restricts access more than Ghardaia does. The Mozabite community that built these towns from the eleventh century has its own distinct Ibadi branch of Islam and its own strict social codes, visible in everything from the walled gardens outside town to the dress of women in the old quarters. Modernist architects, Le Corbusier among them, studied Ghardaia's geometry directly, and the resemblance to buildings you may already know is genuinely striking once it is pointed out.

There is no single gate and no admission fee for the valley as a whole - Ghardaia's old quarter and market can be walked at any daylight hour, busiest in the morning market hours and quieter at midday. Beni Isguen keeps its own, stricter access: non-Muslim visitors are generally admitted only in daylight, dress and behaviour expectations are firmer than in Ghardaia, and photography is restricted in parts of the town - confirm current rules with a local guide before arriving, since they have varied. Friday is a quieter day around the main mosques. There is no public transport running directly between the five towns; a short taxi or a hired car covers the few kilometres between them, and a local guide is the normal way to visit Beni Isguen specifically.
