The La Chapelle-aux-Saints cave, bordering the Sourdoire valley, revealed many archeological artifacts belonging to the late Mousterian techno-complex,[3] including the first ever recognized Neanderthal burial discovered on 3 August 1908.

[4] Jean and Amédée Bouyssonie, as well as L. Bardon, led archaeological digs in the cave from 1905 to 1908, discovering over 1,000 pieces of stone industry (mainly flint), bones of different fauna including reindeer, bovid, horse, fox, wolf and even a rhinoceros’ tooth.

[3] The most spectacular discovery was that of a very well preserved skeleton of an adult Neanderthal man who appears to have been intentionally buried in a rectangular pit 30 centimetres (12 in) deep, 1.45 metres (4.8 ft) long and 1 metre (3.3 ft) wide.

Arguments for the existence of a tomb were the sleeping position of the body, and the funeral "gifts" associated with the pit like stone tools and animal bones.

[3] During the French Revolution, the commune changed its name to La Chapelle-aux-Prés following a decree from the National Convention.
