Menhirs de la Ferme Lambert, Neolithic menhirs at Plateau Lambert, Collobrières, France

The Menhirs de la Ferme Lambert are two standing stones of local micaceous gneiss in a field southeast of Collobrières. The taller, perfectly vertical menhir no. 1 measures 3.15 m high, 0.76 m wide and 0.36 m thick, with the inscription "ROCH 26/6/1967" at its base. Menhir no. 2, slightly tilted, is 2.82 m high, 0.50 m wide and 0.30 m thick. They stand 8.30 m apart.

The menhirs were first mentioned in 1886 by Casimir Bottin and inscribed as monuments historiques in 1988. In 1987, Hélène Barge excavated at their bases and found packing stones but no archaeological artefacts. Commander Laflotte reported that menhir no. 2 had been broken and later re-erected.

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 two menhirs stand in a field by the Ferme Lambert, southeast of Collobrières in the Var. A third, recently discovered menhir was re-erected near the access road to the site. The ground is grass and uneven, so walking shoes are useful; the stones are 8.30 m apart, with the taller one perfectly vertical.

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.
