The site includes human remains, stone tools, and early cultural artifacts made during the Upper Paleolithic, between approximately 47,000 and 17,000 years ago.

The French government classified the site as an historical monument by decree on 25 June 1930, and additional shelters located nearby under the cliff further protected as of May 9, 1958.

In 1958, a small carved female figure was found on a stone about 20 cm (7.9 in) tall, likely dating to approximately 21,000 years BP.

According to Hallam Movius, the figure represents a comparatively young woman, "more slender and gracile than is normally the case," roughly carved, and with contours suggesting pregnancy.

Under the direction of Henry de Lumley, assisted by Brigitte Delluc, a museum was established allowing partial views of excavations.
