December 18, 1994: three amateur speleologists – Eliette Brunel, Jean-Marie Chauvet and Christian Hillaire – discover what will become the Chauvet cave. Closed by a landslide about 20,000 years ago, the place has remained intact until today.

As the light from the fire comes from below, the lighting of the paintings of the restitution must come from the ground. Thus, from the bottom of the footbridges for visitors, low-angle or grazing on the ground, all light sources are not visible to the eye.

The guide that accompanies each group triggers a button for the general rise of the lighting of each station in thirty seconds. The cave then appears as if by magic.

The light design work was done in plan and in section, with the useful support of computer-generated images taking into account the complex geometry of the restitution.

Cave Route For the restoration of the Chauvet cave, the architects Fabre-Speller and Atelier 3A propose a circular building 70 m in diameter integrated into the landscape. The 8,500 m² of the original cave are compacted in anamorphose over 3,000 m². The maximum capacity is estimated at 3700 visitors per day by the delegated company. From the outside, architectonic concrete façades reproduce the principle of the cliffs of the Ardèche gorges.
Inside, accompanied by a guide, the imposed course of the visitors is carried out by group during one hour. The trips are made on a bridge that also serves to hide the projectors.

Without falling into the spectacular, the staging is theatrical but also realistic. To find the atmosphere of the underground environment, the five senses are stimulated. Freshness, humidity, silence, darkness, olfactory sensations help immerse visitors in the world of a cave. Thus, the constant temperature is regulated at 18 ° C.

The visit ends with the large fresco of lions, a monumental panel twelve meters long, from which 92 moving animals emerge.
At the risk of losing all its beautiful treasures and to ensure its conservation, since its discovery, the cave Chauvet can not welcome visitors frequently. How then :
