Origin and history

The Run-er-Sinzen tumulus, located in Erdeven, Morbihan, is an archaeological site dating from the Neolithic period. It consists of a partially ruined tumulus housing two corridor dolmens, one of which, oriented to the east, still retains five support slabs in its funeral chamber. This monument illustrates the collective funeral practices of the period, characteristic of the Breton region.

The site was explored between 1877 and 1878 by G. Chaplain-Duparc, although no detailed reports or results are known to date. Despite its state of degradation, the tumulus and its dolmens were classified as historical monuments by order of 10 May 1926, emphasizing their heritage importance. The better preserved southern dolmen still makes it possible to observe a typical structure of neolithic burials, with a corridor of access and a partially intact burial chamber.

The dolmens of Run-er-Sinzen, sometimes called the Seven Saints, bear witness to the ancient occupation of Erdeven territory. Their presence is part of a larger megalithic landscape, unique to Brittany, where these buildings served both as burial sites and symbolic markers for neolithic communities. Their classification in 1926 preserved this fragile heritage, although their current state remains precarious.

Available sources, including Wikipedia and Monumentum, confirm the approximate address of the site near Kerihuel, as well as its inscription in the Merimée database under Insee code 56054. No information is provided on its current accessibility or tourist use, but its status as a historic monument guarantees its legal protection.
