Les Demoiselles Piquées ('the worm-eaten women') is a small cluster of menhirs forming part of the Saint Just complex. Two of the four stones remain standing, with two fallen off to the east. The largest is around three metres tall. The stones are composed of quartz rock.

According to legend, Les Demoiselles Piquées were petrified by God for dancing on the moors on a Sunday rather than attending church.

These are big, impressive megaliths, quite different to the Moulin de Cojoux alignment a short distance away. Those stones are slender and knife-like, whereas these are bulky and squat.
