Origin and history
The terre of the farm of Saint-Urnel in Plomeur is a monument dated from the High Middle Ages, located in Finistère in Brittany. This archaeological site is distinguished by the presence of megaliths surrounding it, reflecting an ancient occupation and a possible ritual or funeral function. The classification of the terter and its megaliths by decree of 30 July 1929 underlines its heritage importance and the desire to preserve this emblematic vestige of Breton history.
The location of the terre, near the farm of Saint-Urnel, is indicated with an accuracy considered "passible" (note 5/10), according to the available data. The official address referenced in the Mérimée database corresponds to INSEE code 29171, attached to the municipality of Plomer in the district of Quimper. Although the practical information on openness to the public is not detailed, the site remains a major historical marker to understand the practices and spatial organization of the High Middle Ages communities in Brittany.
Available sources, including Monumentum, confirm that the terten and its associated megaliths (cadastre A 19, 21, 936, 937, 938) constitute a protected whole. This ranking reflects the archaeological interest of the site, probably linked to cultural or religious practices prior to the medieval period. No additional information is provided on any artifacts discovered or on recent excavations, limiting accurate knowledge of its past use.
