The Ardèche or Ardacha region, so-named for a tributary of the Rhône, is one of the most important and older districts of modern human presence in SW Europe. Its importance was underlined with the discovery of the Grôte Chauvet, the cave of lions.
Now another discovery has been made in the same area with a decoration of what seems to be a horse head. The finding actually was made in 2011 by some speleologist but kept secret till it was researched preliminarily.
