Origin and history
The sepulchral room of Kersaint-Plabennec is a prehistoric monument originally located in the tumulus of the village, on the town hall square. This archaeological site, typical of the funeral buildings of Prehistory, was classified as a Historical Monument by decree of 29 March 1950, before being declassified on 15 March 1967. Today, it was destroyed, showing ancient funeral practices in the Breton region, although its precise location remains approximate (level of accuracy: 4/10 depending on the sources).
The monument belonged to the commune of Kersaint-Plabennec, in Finistère (Department 29), and was referenced under cadastre C 341. Available data from Monumentum and the Merimée archives indicate that it was a protected structure before its disappearance. No information is provided on its current accessibility, tourist use or material preservation, other than its official decommissioning.
In prehistoric times, the sepulchral chambers such as Kersaint-Plabennec served as places of collective burial, reflecting the beliefs and social organization of neolithic communities. These structures, often integrated into tumulus, marked the landscape and played a strong symbolic role. In Brittany, a region rich in megaliths, such monuments illustrated the gradual sedentarization and worship of ancestors, although their specific details depend on archaeological excavations, here absent or undocumented.
