22 Places You Are NOT Allowed To Visit… #3 Is Hiding Earth’s Biggest Secret.


You’ve learned about these Palaeolithic cave paintings, most prominently the Great Hall of the Bulls, in art history. Lascaux was discovered in southwestern France in September 1940, enriching the world with prehistoric art telling of human origins.

In 1979, together with other caves in the Vézère Valley, Lascaux was honored as a UNESCO World Heritage Site. Though visitors were allowed access to the cave in previous years, a fungus was discovered. It was believed to be caused by the newly installed air conditioning system, high powered lights, and frequent visitors. The situation has become even more serious in recent years, with authorities closing the cave for three months in 2008, even for qualified researchers.
