Origin and history

The Menhir de la Haute-Pierre is an iconic megalithic monument located at the Feu Lambert in the commune of Champeaux, Ille-et-Vilaine. This quartzite block, with a height of 4.07 meters and a maximum width of 1.85 meters at its base, is distinguished by its shape of a four-sided oblique pyramid trunk, topped by a spherical cap deformed by erosion. It stands isolated in a field, above a valley, about 2 km southeast of the village of Champeaux and 500 m northwest of the Cantache Dam. Its alignment with two other menhirs, located on the neighbouring municipality of Pocé-les-Bois (the Pierre Blanche à l'Égalerie and another in Villaumur), suggests an intentional organization, typical of the megalithic constructions of this period.

The Menhir was officially recognized for its heritage importance and listed in the inventory of historical monuments by a decree of 28 May 1980. This protection reflects its archaeological value and its role in understanding the cultural and religious practices of Neolithic in Brittany. The studies conducted, notably by archaeologists such as Jacques Briard, Loïc Langouët and Yvan Onnée, have helped document this site among the many megaliths in the department of Ille-et-Vilaine. The menhir, although located in rural areas, remains accessible and offers a remarkable example of Breton megalithic architecture, marked by the use of local stones such as quartzite.

The geographical context of the menhir, between the so-called places of Feu-Lambert and the Vallons, and its proximity to other menhirs, reinforces the hypothesis of a sacred or ritual landscape organized by the Neolithic communities. These monuments, often associated with funeral or astronomical practices, illustrate the technical and symbolic mastery of the societies of the period. Their preservation makes it possible today to study the lifestyles, beliefs and cultural exchanges that animated Brittany more than 5,000 years ago.
