About 15,000 years old, rock shelters at the foot of cliffs were occupied by Magdalenians, whose used their technical skills to create surfaces suitable for sculpting. The Roc-aux-Sorciers site is a excellent example of this use of rock walls. Practices observed at Roc-aux-Sorciers can be found at other sites, including Cap Blanc, Chaire-à-Calvin, Reverdit, etc., even though each site has its own specificities. From this point of view, Roc-aux-Sorciers can be seen as a model.
