Lascaux 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.[1][2] They primarily consist of primitive 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.

The cave was discovered on September 12, 1940 by four teenagers, Marcel Ravidat, Jacques Marsal, Georges Agnel, and Simon Coencas, as well as Marcel's dog, Robot.[4] The cave complex was opened to the public in 1948.[5] By 1955, the carbon dioxide produced by 1,200 visitors per day had visibly damaged the paintings. The cave was closed to the public in 1963 in order to preserve the art. After the cave was closed, the paintings were restored to their original state, and were monitored on a daily basis. Rooms in the cave include The Hall of the Bulls, the Passageway, the Shaft, the Nave, the Apse, and the Chamber of Felines.
