The Tassili n’Ajjer National Park, UNESCO World Heritage Site since 1982, is an outstanding plateau of about 70.000 km² composed mostly of black and red sandstone that, due to the erosion, has spectacular shapes of canyons, natural rock arches and volcanic ridges.

The National Park, located in the south-eastern area of Algeria at the borders of Mali, Niger and Libya, reachable from the town of Djanet, is one of the most important archaeological sites in the world, with a well-preserved collection of remains and over 15,000 rock engravings and drawings dating back to the Neolithic era.
