French President Francois Hollande (R) listens to explanations of Pascal Terrasse, President of the Cavern of Pont-d'Arc project, during its inauguration visit in Vallon Pont d'Arc April 10, 2015. The Cavern of Pont-d'Arc project is a replica of the pre-historic decorated Cave of Pont-d'Arc known as Grotte Chauvet, in Vallon Pont-d'Arc in the Ardeche region, containing the world's earliest known art which was recently named a UNESCO World Heritage site. The facsimile cavern, which condenses some 8000m2 of the original site into 3000m2, will display faithful reproductions of paintings and engravings and will open to the public on April 25.
