[2] It consists of a straight gallery about 100 m (330 ft) long with parietal art along the entire length of the cave.

[3] The art includes human and animal (bison and horses) figures as well as geometric forms and has been described as being of "profound stylistic originality with few equivalents in the region from the same period".

Excavations have been carried out since at least 1883 by a number of researchers including Henri Breuil and André Leroi-Gourhan and between these and the visitors attracted by the many publications describing the cave (the first was published in 1885), virtually all the easily accessible surfaces were damaged.

Engravings and paintings found in the cave have been dated to around 17,000 BP and an extensive program of photographing the decorated panels has been undertaken.

[3] A conch from 18000 years BP found in the cave in 1931 was demonstrated in 2021 as having been adapted by Magdalenian people as a musical instrument.
