Join euronews correspondent Olivier Peguy on a trip inside a mountain.
“I’m in the French Alps, in the heart of the Vercors Massif, where I am literally going into the heart of the mountain, to the Choranche cave. It is one of the most beautiful in France and has a new sound and light spectacle as you can see in the video and in 360 degrees,” Olivier reported from the mountain side.
Local villagers discovered the cave at the end of the 19th century.
Teams of speleologists – experts who make a scientific study of caves – followed underground rivers to find the caves.The galleries go on for tens of kilometres but only a small section is accessible to the public.
It took millions of years to shape the underground landscapes.
One of the most remarkable parts of the cave is the “fistulous”. Those are very fine stalactites formed of a natural tube of concentrated calcite.
These “tubes” grow an average of five centimeters in 100 years. The longest is 3.20 meters.
A little further on you come into a huge cavity called “the cathedral”. This is where the new sound and light show can be seen. It made its debut at the weekend.
“This big room, 30 meters high, 50 meters wide and 90 meters long could be overwhelming. We could feel lost. Well, I think that this show, on the contrary, will give the cavity a softness and a human side with these small soft touches revealing the place. Throughout the whole show you get a feeling of peace and of pleasure, concluded Laurent Garnier, Choranche Cave Director.
