Origin and history

The Pierre Courcoulée, also known as Pierre des Huguenots, is a covered driveway located in Landéan, Ille-et-Vilaine. This megalithic Neolithic monument consists of a partially ruined granite structure measuring 6 metres long and 1.30 metres wide. It is bounded by twelve orthostats, one of which is reversed, and was originally covered with one or two slabs of cover, according to the interpretations of archaeologists P. Bézier and L. Collin.

The building has been classified as historic monuments since December 19, 1946, along with the adjacent line of the Druids Cordon. These two sites, located in the Fougères forest, demonstrate the importance of megalithic constructions in this Breton region. The granite blocks used and the covered aisle structure suggest a funeral or ritual use, typical of neolithic practices.

The historical descriptions come mainly from the work of Paul Bézier (1883), who evokes a single cover table of 4.08 metres long, and of L. Collin (1931), which proposes the hypothesis of two distinct slabs. These differences illustrate the challenges posed by the study of prehistoric monuments, often fragmentary. The site remains a remarkable example of Breton's megalithic heritage, studied and referenced in specialized works such as Jacques Briard (2004).
