The region of Tassili N’ajjer, vast sandstone plateau of lunar aspect, is of a great beauty. It is considered to be the largest open-air museum of rock art in the world: more than 15,000 drawings and engravings tell about the climate, wildlife and human life in the Sahara. It is estimated that its oldest remains date back to 6,000 BC.
Djanet:
At the foot of the N’Ajjer massif, about 700 kilometers east of Tamanrasset, Djanet appears as an oasis with a sweet and relaxing charm. It is very different from Tamanrasset while being its almost indispensable complement. Its three ksour and six districts, classified as World Heritage by the UNESCO, were built about ten centuries ago, against the granite rocks, to monitor the gardens of the palm grove and protect themselves from the floods of the wadi. Azellouaz, with its whitewashed mosque, is the oldest district of the city.
The city today has nearly 15,000 inhabitants, mainly Tuaregs.
