Polissoirs de Coinche

Polissoirs de Coinche consists of two fixed polishing stones made from fine Ypresian sandstone, with one bearing three grooves, five basins, and a polishing surface. These stones sit alongside a menhir, forming a prehistoric complex that has remained in its original location.

The site originates from the Neolithic period and documents prehistoric craft techniques. It received protected historical monument status in 1986.

The site shows how early inhabitants of the area shaped and refined their tools through daily work. These stones stand as evidence of practical skills passed down through generations of craftspeople.

The stones are located in an open outdoor setting and are accessible at all times. Sturdy footwear is recommended, as the terrain can be rough and uneven.

A third portable polishing stone was discovered in 1982 near the menhir. This finding expanded understanding of prehistoric activities that took place at the location.
