Origin and history

The Pierre Saint-Benoit is a neolithic polisher located in Saint-James, in the department of La Manche, on the former parish of Saint-Benoît. This monument, consisting of a block of triangular white quartzite (1.50 m long and 0.60 m wide), emerges slightly from the ground and has sixteen grooves as well as an elliptical bowl 25 cm long. The proximity of a creek probably facilitated the polishing of stone tools.

In 1881, a certain Briant was said to have undertaken excavations around the block, revealing that he was sinking about 2 metres into the ground. On this occasion, three polished axes, including a discovery at the foot of the polisher, were discovered in the surrounding area. These artifacts attest to the intensive use of the site for tool making or sharpening during Neolithic.

The canon Pigeon, quoted by Léon Coutil, retained several lithic tools found nearby, including a jadeite perforated axe, a pink pegmatite herminette, and a perforated hammer axe. These vestiges, now extinct or dispersed, illustrate the diversity of size techniques and materials used by local neolithic communities. The polisher was classified as historical monuments by decree of 5 December 1977, thus recognizing its archaeological importance.

Pierre Saint-Benoit is part of a wider network of megalithic sites in the English Channel, reflecting the artisanal practices and cultural exchanges of the time. Its state of conservation and its approximate location (5775 La Villette, Saint-James) make it a rare example of polishing still in place, although its geographical accuracy is considered poor (level 5 out of 10).
