Origin and history

Kerviniou Dolmen, located in Guiscriff, Morbihan, is a covered alley dating from the Neolithic period. This megalithic monument, typical of the Breton region, was originally used as a collective burial. It is located in a field, about 100 metres north of the hamlet of Kerviniou, and has been partially damaged by clandestine excavations and agricultural work.

Ranked as historical monuments by two successive decrees in 1930 and 1934, the dolmen is about 10 metres long and is oriented southeast/northwest. It consists of a small terminal cell at its southeast end and an access corridor of approximately 1.40 m wide. A transverse slab near the entrance delimits a vestibule, characteristic of the covered aisles of this period.

Historical sources, including the works of Philippe Gouézin, underline the archaeological importance of this site among the megaliths of Morbihan. The monument is referenced in the Merimée base under INSEE code 56081, confirming its membership in the municipality of Guiscriff. Despite its altered state, it remains a valuable testimony of neolithic funeral practices in Brittany.
