10 Forbidden Places No One Will Ever Be Allowed to Visit

Reader's Digest Logo By Marissa Laliberte of Reader's Digest | Slide 1 of 11: The prehistoric paintings in the Lascaux cave were found in 1940, and it became a tourist site after World War II. The carbon monoxide from visitors’ breath started to damage the cave paintings, which are now named a UNESCO World Heritage Site, and the cave closed to the public in 1963. Replicas opened for business after it closed, but only preservationists and researchers are allowed in the original. Check out some of the UNESCO World Heritage Sites you can (and should) visit.

Might as well leave these ones off your bucket list.
