Origin and history

The Dolmen du Moulin-des-Oies, also known as Boccénic Vras, is an iconic megalithic monument located in Belz, Morbihan department. This corridor dolmen, facing east, is distinguished by its circular chamber of approximately 4.30 meters in diameter, bounded by nine orthostates in local granite. A corridor, supported by five slabs, extends this central space, illustrating a typical architecture of Neolithic collective burials.

The site was first reported by W. C. Lukis and then explored in 1877 by Chaplain-Duparc, although the results of this exploration remain unknown. In 1931, Zacharie Le Rouzic undertook a controversial restoration of the dolmen, modifying its room to give it a rectangular shape, thus moving away from its original configuration. Archaeological objects discovered during these interventions (pottery fragments, flint tools) are now preserved at the Museum of Prehistory in Carnac.

Ranked under the title of historical monuments by order of 24 July 2023, the dolmen is situated on a submersible point of the public maritime domain, near the river d'Etel. Its tumulus and structure, although partially altered, reflect complex funeral and social practices of Breton Neolithic communities. Local granite slabs and the strategic position of the site underline its symbolic and practical importance in the regional megalithic landscape.

Historical sources, notably the works of Philippe Gouézin and Zacharie Le Rouzic, document this monument as a notable example of Morbihanian megalithism. Its recent listing among protected monuments reflects a desire to preserve this fragile heritage, exposed to natural hazards and human transformations. Dolmen remains a subject of study to understand funeral rites and the spatial organization of Neolithic societies in Brittany.
