Many of the stones were discovered lying prone and buried under vegetation before being re-erected in their probable original positions.
The site features a permanent outdoor exhibition dedicated to the 'experimental archaeology' of megalithic movement.
The majority of the stones are made of purple schist, a local rock type sourced from nearby quarries.
Archaeologists found over 400 stone fragments during the excavation of this 1.5-hectare site.
The stones range in size, with some reaching up to 3 meters in height.
Carbon dating of charcoal found in the pits suggests human activity on the site dating back to the Neolithic period.
The alignment orientation appears linked to the topography of the local valley.
Volunteers and students frequently participate in the site's ongoing experimental research projects.
The park was designed to incorporate the alignment into a trail that preserves the local biodiversity of the heather and gorse environment.
The site includes a reconstruction of a megalithic transport trackway to demonstrate how heavy stones were moved.
The Menhirs of Monteneuf consist of an alignment of approximately 40 standing stones located in a protected natural park in Brittany. These Neolithic monuments were discovered in 1989 and underwent significant archaeological excavation and re-erection. The site functions as an open-air laboratory where researchers study the techniques of megalithic transport and construction. Unlike many other Breton sites, the stones are arranged in a specific pattern within a heathland landscape. Visitors can observe the raw stone extraction sites and experimental areas where stones are moved using prehistoric methods. The surrounding terrain is characterized by schist, which is the material used for the majority of the menhirs. The site is actively managed to preserve its archaeological integrity while offering public educational access. It remains a focal point for understanding the social organization of Neolithic groups in the Brocéliande region.
The elevated viewing platform at the edge of the alignment provides a comprehensive angle of the stone rows against the forest backdrop.
Wear sturdy, waterproof hiking shoes as the terrain is natural heathland and can be muddy.
Bring binoculars to view the distant landscape markers from the highest points of the path.
Check the official website for scheduled demonstration days where staff practice moving stones using ancient techniques.
Do not wander into the surrounding private agricultural fields, as the marked site boundaries are specific to the protected area.
The site is typically closed during the winter months and transitions to limited weekend operations in the shoulder seasons.
Do not climb on the stones and stay strictly within the marked trails to protect the fragile heathland ecosystem.
