The old city is an extraordinary example of Saharan domestic architecture: a labyrinth of connected covered alleyways allowing movement across the entire settlement without ever entering direct desert sun, with upper-level pedestrian bridges between houses and whitewashed gypsum walls that regulate interior temperature without any mechanical cooling.
