Tucked away inside a limestone cave in southeastern France lies some of the oldest artwork in existence. Known as Chauvet Cave, the site is so historically important—and fragile—that its location is kept secret and the cave is locked behind a huge steel door. And now, researchers

Tucked away inside a limestone cave in southeastern France lies some of the oldest artwork in existence.
