The dolmens, covered with Mezerma and their tumulus, as well as the base soil of plots D 432 and D 433 and the base soil of part of plots B 171, B 172, B 173 and D 431 constituting an archaeological reserve. This set appears in the cadastre of the commune section B parcels No 171, 172 and 173, and section D parcels No 431, 432 and 433, shown on the plan attached to the decree: inscription by order of 24 July 2023
Origin and history
The megalithic complex of Mezerma, located in the municipality of Carnac in Morbihan (Bretagne), is a major architectural testimony of Neolithic. This site includes several dolmens, a covered driveway and their tumulus, protected for their archaeological value. The parcels concerned, identified in the local cadastre (sections B and D), were officially listed as Historic Monument by ministerial decree in July 2023.
The location of the site, although documented in official bases such as Mérimée, remains approximate according to the geographical accuracy criteria (note of 5/10). Protected elements include not only visible megalithic structures, but also the soil of surrounding plots, designated as an archaeological reserve to preserve possible buried remains.
In Neolithic, Breton communities erected collective funeral monuments such as dolmens and covered alleys, reflecting a complex social organization and beliefs related to death. These structures served as both burials and territorial markers, integrated into sacralized landscapes. Their construction required Community cooperation and advanced technical knowledge for stonework.
The recent inscription (2023) of the whole of Mézerma underscores its heritage importance, although available sources (such as Monumentum) do not detail its precise use or event history. The site is part of a wider network of Carnaco megaliths, famous for its exceptional concentration of prehistoric monuments.
No information is provided on public access, visit or related services (such as guest rooms). The data are limited to legal and geographical aspects, without reference to recent excavations or specific archaeological discoveries on this site.
The site protection covers both the visible structures and the subsoil of adjacent plots, suggesting an unexplored archaeological potential. This measure aims to preserve the integrity of the funeral and ritual context, characteristic of the Breton megalithic ensembles of this period.
