Neandertal men, then homo-sapiens and especially Magdalenians, have always been sheltered in the natural habitats of caves and rock shelters. Archaeologists find many traces of these prehistoric habitats accumulated in successive layers.

It is in these caves that we find ornaments as in the caves of Lascaux, Chauvet. All these testimonies take the form of drawings, paintings, engravings, sculptures executed on the walls.
