The wall art at Roc-aux-Sorciers is basically found in two areas: on the ceiling of the Taillebourg Cave (unfortunately collapsed) and at the head of the Bourdois Shelter.

This division is connected with the excavated sectors. A sondage by Suzanne de Saint-Mathurin revealed traces of wall sculptures between the two areas, at the level of the archaeological reserve. Farther downstream, a sculpture has not been completely excavated, leaving the impression that the wall art continues further and deeper than the 50 metres uncovered to date.

A separate set of wall engravings lie beneath the monumental sculptures. An analysis of the sculpted ensemble shows that it was organised by register and by theme, both at the back of the shelter and on the ceiling. Several re-cuts reveal that the images have been reworked.
