The Oued Djerat is a wadi located south of Illizi. It leads through a remote rock valley in the Tassili n'Ajjer National Park, which has thousands of rock paintings, mostly rock paintings, but also petroglyphs. The picture gallery stretches for many kilometres. What is unusual in this region is that the pictures are particularly large. Giraffes alone are depicted on an area of 100 m², the largest of which measures eight metres. The discovery for the public dates back to 1934, when the French officer Brenans stopped at this place with his troop and came across the drawings of rhinos, hippos, crocodiles, elephants and giraffes. The French explorer Henri Lhote picked up the thread and discovered thousands of other drawings, which he studied scientifically. The petroglyphs date back to the Neolithic period and show similarities to those in the provinces of Oran (Algeria) and Fessan (Libya). According to Henri Lhote, they date back more than 7000 years. - Algeria - 1966
