Gallo-Roman Millstone Quarry

Here, the pile of imperfect millstones left on the site by the grinders and the circular cuts in the quarry, still visible in the negative, bear witness to the mining activity on this site in Roman times.
The quarry was discovered in 1943 when human bones were unearthed during municipal work. In 2018, the cantonal archaeology department cleaned the site, which was gradually covered with moss and earth: the traces of the cuts are clearly visible again.
The six educational panels on the site provide information on the discovery of the site, the historical context of the region, the technique of millstone extraction, its use in Roman mills, the shell sandstone and its geology.
