The tumulus (Case M 561): classification by decree of 10 May 1926, declassified by official gazette of 15 March 1967
Origin and history
The mound of Er-Run-Bras, located in Erdeven, Morbihan, England, is a neolithic funerary monument. This type of structure, typical of the period, generally served as a collective burial and marked the landscape of its imposing presence, reflecting the cultural and religious practices of the local communities of the time.
Filed by order of 10 May 1926, the tumulus was then declassified by a decree published in the Official Journal on 15 March 1967. The reasons for this downgrading are not specified in available sources, but this administrative evolution illustrates the changes in heritage conservation policies over the 20th century. The location of the site, reported as approximate (accuracy note: 5/10), is located near Saint-Germain, according to the GPS coordinates recorded.
In the Neolithic era, Brittany was a region where sedentary communities developed nascent agriculture and raised livestock. The tumulus, like Er-Run-Bras, played a central role in funeral rites and social structure, serving both as territorial markers and as places of memory for successive generations. Their construction required a collective organisation, reflecting an already hierarchical society capable of mobilizing important human resources.
Today, the tumulus does not seem open to visit according to available practical information. Its current status and accessibility remain unclear, although its location is listed in the Mérimée database under the code Insee 56054, attached to the town of Erdeven. The sources mentioned (Monumentum, internal data) do not provide additional details of its conservation status or any archaeological excavations at the site.
