Pierre blanche menhir

The Pierre Blanche menhir is an upright stone block from the Neolithic period standing in Oudon, Loire-Atlantique, rising as a solitary monument in the landscape. The structure marks a site of prehistoric importance and is now protected as an archaeological location.

This stone block was erected during the Neolithic period and belongs to a group of megalithic monuments left by prehistoric civilizations in the region. Its age spans several thousand years and reflects early human activity in western France.

The menhir represents a link between prehistoric communities and the western French landscape. It shows how megalithic structures held importance for early peoples in marking territory and community identity.

The menhir sits in open terrain and is reachable on foot via local paths, with best conditions during fair weather. Visitors should wear sturdy footwear and be prepared to explore the immediate surroundings independently.

The stone remained hidden beneath earth and vegetation for centuries and was fully uncovered through archaeological investigation in more recent times. This rediscovery helped researchers better understand the prehistoric network of monuments across the region.
