Ardèche is a department in south-central France named after the Ardèche River.The area has been inhabited by humans at least since the Upper Paleolithic, as attested by the famous cave paintings at Chauvet Pont d'Arc. The plateau of the Ardeche River has extensive standing stones (dolmens and menhirs), erected thousands of years ago. The river is the largest natural canyon in Europe and the caves that dot the cliffs (which go as high as 300M(1,000 feet)) are known for signs of prehistoric inhabitants (arrowheads and flint knives are often found.)
