The mineral landscape carved by the glacier trajectory about 10,000 years ago contains an archaeological treasure of about thirty to forty thousand rock carvings around Mount Bego, mostly dated about 3000 to 1600 BC.
Rediscovered by scholars at the end of the 19th century, the engravings are found on rock faces, and more frequently on rocky outcrops (“moutonnées” rocks) or erratic blocks (mainly pelite and sandstone).
Since the end of the Neolithic, during the metal ages, then during the Roman period and finally during the medieval and modern eras, the men and women present on these sites of high mountain left various symbolic representations.
Cattle engravings, couplers, weapons and geometric figures were made during Protohistory, while the motifs of coats of arms, firearms, texts and pastoral and popular designs are historical.
