Origin and history

The Dolmen de Roscoualc'h, also called Karreg-An-Aour, is a megalithic monument located in Trédrez-Locquémeau, in the Côtes-d'Armor department in Brittany. This small corridor dolmen, consisting of eight shale orthostates, is covered with a single partially collapsed cover table. The whole remains enclosed in a circular cairn measuring between 20 and 30 meters in diameter, typical of the Neolithic buildings of the region.

Classified as historical monuments since 7 July 1982, this site is owned by the department. The roof table is 2.50 m long for 2.15 m wide and 0.50 m thick, while the bedroom opens to the east and the corridor to the north. According to local traditions, an old man with a large hat would have lived in the dolmen, hiding a treasure and only leaving at night. This monument could correspond to Keranvilin's aisle-coverage, mentioned in old inventories.

Excavations and studies, such as those conducted by Anne Marchat and Michelle Le Brozec in 1991, highlight the importance of megaliths in the Lannion district. These funeral or ritual structures testify to the cultural and social practices of neolithic communities in Brittany. The dolmen of Roscoualc'h, with its preserved cairn, offers a remarkable example of this megalithic heritage still visible today.
