Origin and history

The Menhir de la Roche Longue, located in the town of Quintin in Côtes-d'Armor, is a megalithic monument emblematic of the Neolithic period. This granite block, crossed by a quartzite sill, reaches 7 meters in height with a width of 2.10 meters and a maximum thickness of 1.20 meters. Its impressive stature makes it a remarkable testimony to the architectural and cultural practices of prehistoric societies in the region.

Ranked as historical monuments in 1862, the Long Rock attracted the attention of intellectuals and historians, including Prosper Mérimée, who visited the site in 1836. This early ranking underscores its heritage importance and its role in understanding Breton megalithism. Menhir, still visible today, remains a symbol of the funeral or ritual traditions of Neolithic, although its exact uses remain partially mysterious.

The location of the menhir, at approximately 18 Rue de la Fosse Malard in Quintin, is documented in heritage bases such as Mérimée. Its state of conservation and accessibility make it a point of interest for those passionate about history and archaeology. The granite stone and the presence of quartzite add a geological dimension to his study, reflecting the natural resources exploited by the Neolithic builders.
