Tassili n'Ajjer is a vast desert plateau in southern Algeria, stretching from the borders with Niger and Libya to the east, to as far as Amguid in the west, covering an area of 72,000 sq. km. Thousands of years of changing Saharan climate and erosion have created stunning geological features with towering sandstone pillars, deep canyons and more than 300 natural arches.
Tassili n'Ajjer shot into worldwide fame in the 1930s, not for its landscape but for the precious collection of ancient rock art in the area. Since their discovery, more than 15,000 petroglyphs and paintings have been identified representing 10,000 years of human history and environmental change. One of the most striking feature of these petroglyphs is the way they evolved with the change in climate.
