Menhirs de la Ferme Lambert

The Menhirs of Ferme Lambert are two upright stone monoliths made of local micaceous gneiss, standing on a plateau near Collobrières and measuring roughly 3 meters and 2.80 meters in height. They stand separated by about 8 meters and form the primary stones of this megalithic site.

These stones were raised during the Neolithic period when people in the region created megalithic monuments as part of their cultural practices. Archaeological study in the 1980s documented evidence of early activity at the base of the stones.

Local stories connect these stones to a hidden tunnel that monks reportedly dug, leading beneath the earth toward the Carthusian monastery of Verne. Such tales shape how visitors experience the site and what meaning they find in standing before ancient stone.

The site is accessible from Collobrières village via the GR90 hiking trail, which winds through the forest and is marked with red and white blazes. The terrain is hilly, so visitors should wear suitable footwear for walking on uneven ground.

A third stone was discovered later and replanted near the access road, revealing that the original site was larger than initially believed. This finding expands our understanding of what the complete megalithic complex once contained.
