Origin and history

The Menhir de Pierre-Pin, also known as Pierre des Huguenots, is a megalithic monument located in the municipality of Sion-les-Mines, in the Loire-Atlantique department, in the Pays de la Loire region. This massive trapezoidal block is 2.60 metres high, with a respective width and thickness of 2.60 m and 1.40 m at its base. Its alternative name evokes a possible historical association with the Huguenots, although this origin is not explicitly documented in available sources.

The menhir was listed as historic monuments on 14 June 1988, recognizing its heritage value. This official protection underlines its archaeological and cultural importance in the megalithic landscape of the Loire-Atlantique. The bibliographical references, such as the Archaeological Dictionary of the Loire-Inferior (1882) by Pitre de Lisle du Dreneuc, attest to his study since the 19th century, although the details of his erection or his original function remain absent from the sources.

The location of the menhir, near the Haute Noé on the municipality of Sion-les-Mines, is specified by GPS coordinates and an approximate address in the Mérimée base. The site, although protected, does not have detailed information about its accessibility or contemporary use, such as a tourist visit or a commemorative function. Its state of conservation and immediate environment are not described in the sources consulted.
