The prehistoric cave paintings in France are found in Lascaux, a cave network near Montignac in Dordogne.
Lascaux’s walls and ceilings feature hundreds of painted and engraved images, especially horses, aurochs, deer, and other animals known from the Upper Paleolithic environment. The paintings are generally dated to around 17,000 to 22,000 years ago, although questions about their precise chronology and cultural attribution remain.
The cave entrance was discovered on 12 September 1940 by Marcel Ravidat after his dog investigated a hole near an uprooted tree. Lascaux opened to visitors in 1948, but large crowds and altered air conditions contributed to serious conservation problems. The original cave was closed to the public in 1963.
Visitors now see carefully made replicas, including Lascaux II and later presentation sites. Lascaux is sometimes compared with Altamira in Spain, but Altamira is a different painted cave and is not the answer to this question.
