From the 147 prehistoric sites of the Vézère valley I only have postcards of Lascaux. Two of them I bought them in my last trip but I didn't visit the place....

The Vézère valley contains 147 prehistoric sites dating from the Palaeolithic and 25 decorated caves. It is particularly interesting from an ethnological and anthropological, as well as an aesthetic point of view because of its cave paintings, especially those of the Lascaux Cave, whose discovery in 1940 was of great importance for the history of prehistoric art. The hunting scenes show some 100 animal figures, which are remarkable for their detail, rich colours and lifelike quality. - in: http://whc.unesco.org/en/list/85
Lascaux (Lascaux Caves) is the setting of a complex of caves in southwestern France famous for its Paleolithic cave paintings. The original caves are located near the village of Montignac, in the department of Dordogne. They contain some of the best-known Upper Paleolithic art. These paintings are estimated to be 17,300 years old. They primarily consist of images of large animals, most of which are known from fossil evidence to have lived in the area at the time. In 1979, Lascaux was added to the UNESCO World Heritage Sites list along with other prehistoric sites in the Vézère valley. - in: wikipedia
The cave contains nearly 2,000 figures, which can be grouped into three main categories: animals, human figures, and abstract signs. The paintings contain no images of the surrounding landscape or the vegetation of the time. Most of the major images have been painted onto the walls using red, yellow, and black colours from a complex multiplicity of mineral pigments including iron compounds such as iron oxide (ochre) haematite, and goethite, as well as manganese-containing pigments. - in: wikipedia
