Pierre Tourneresse, Neolithic passage grave in Cairon, France
The circular mound structure extends 24 meters in diameter with two burial chambers connected by an 8-meter corridor lined with limestone walls.
Archaeological excavations between 1996 and 1999 uncovered evidence of human settlements dating back to 4400 BCE beneath the funerary monument.
The remains of eight adults and one child were discovered in the chambers, along with ceramic fragments from the northern Chasséen civilization.
The archaeological site stands north of Cairon municipality and contains preserved stone chambers that visitors can observe from designated viewing areas.
Carbon dating of human bones found in the main chamber indicates burial activities occurred between 3900 and 3700 BCE during the Neolithic period.

Throughout France, stone silhouettes still stand in fields, forests, or by the sea. They existed long before villages and roads, witnesses to a world that believed in the sky and hidden forces of the earth. These menhirs, erected over five thousand years ago, in their own way narrate the dawn of civilizations. Some are solitary, others are arranged in rows of hundreds. Some bear engraved faces, others remain silent, smoothed by Breton winds or the rain of the Central Massif. From Carnac to Corsica, from Poitou to the Côtes-d’Armor, these upright stones maintain a strong presence, almost human. Approaching them, one senses the ancient connection between human hands and the memory of the land.
