The Bec Moler quarry, used as a silica quarry for the Vernante glassworks, was cultivated until the 1960s, when it was abandoned in favor of more profitable quarries in the municipality of Robilante. The main access gallery is still passable and allows you to observe the quarry from above.Before mining began, the millstones (or grindstones) for the mills were obtained from the Bec Moler, a fact which explains the toponym of the mountain. With a bit of attention it is still possible to observe on the rocky walls the circular carvings from which the millstones were extracted. The extraction was not always successful, as evidenced by a millstone which broke during the extraction phase and is still partly attached to the parent rock.
