2. Lascaux Caves – France
You used to be able to go into the Lascaux Caves up until 1963, which is when they became close to the public due to a fungus that was spreading through them.
What’s so special about these caves you ask? Well, they’re the site of the oldest and largest cave drawings in the world, dating back around 20,000 years and including a 5.2m long bull.
If you want to see the drawings though then don’t fret! You can visit a purpose-built replica cave near the actual cave that was created to help preserve the magnificent history that is contained in the real thing.
