To protect its preservation, it currently allows only 5 people to visit it per week and this is the reason they created this replica from the cave. The cave is a natural cavity in the rock, with paintings dated from 35,600 years ago and it stands as one of the most important pictorial and artistic cycles of prehistoric paintings int he world.
