The Lascaux Caves are caves that have some of the finest examples of prehistoric cave art ever found. Shockingly, they were once open to the public.

Therefore, visitors are banned from seeing the original caves, and are instead encouraged to see the incredible recreations instead!

There is absolutely no way of getting inside Room 39 – and you wouldn’t even want to attempt to.
