The Dordogne, France: Lascaux’s Prehistoric Cave Paintings
On a September day in 1940 while much of Europe was engulfed in war, four teenagers were walking through a forest in southern France when their dog fell down a hole.
As they called for it they heard an echo. Crawling in to rescue the dog, the boys discovered a cave with hundreds of prehistoric animals painted across its walls and ceiling. It turned out to be one of the world’s best examples of prehistoric art.
