Pierre Tourneresse

Pierre Tourneresse is a megalithic passage grave north of Cairon with a circular mound structure. The site contains two connected burial chambers linked by a stone corridor built with limestone walls.

This passage grave was built during the Neolithic period and served multiple generations as a burial place. Evidence found during excavations shows that people had inhabited the area before the monument was constructed.

The name comes from Pierre Tourneresse, the farmer on whose land this site was discovered. Visitors walking through can sense how this ancient community marked death and honored their members in stone.

The stone chambers can be viewed from designated observation areas around the site. Wear comfortable shoes since you will be walking outdoors on uneven ground near the mound.

Excavation teams discovered ceramic fragments inside that suggest connections with northern populations of the time. These findings reveal that ancient communities here exchanged goods and ideas across considerable distances.
