Origin and history
The archaeological site of Old St. Yves, located in Bubry, Morbihan, is a fortified complex dating from the middle of the Middle Ages. It consists of a castral moth of truncated shape, 8 to 9 meters high and surrounded by a ditch, as well as a semi-elliptic bassyard protected by earth lifts. These remains illustrate a defensive architecture typical of the medieval era, with a structure designed to control and protect a territory.
The castral moth, with a diameter of about 50 meters, is girded by a ditch of 5 to 6 meters wide, partially destroyed by the development of a road. The lower courtyard, located to the west, retains traces of observed stone buildings until 1990. This site was the seat of the Kernivinian seigneury, reflecting its local importance in the feudal organization of the region.
The entire site, including the surrounding parcels, was listed as historical monuments by order of 28 November 1995. Despite some degradation, such as partial destruction of the sommital platform by a trench, the site remains well preserved. It offers a valuable testimony to the techniques of fortification and seigneurial occupation in Brittany in the Middle Ages.
Located about 4 km south of the village of Bubry, near the hamlet of Old Saint-Yves, this monument is a representative example of Breton castral mottes. These structures played a key role in defending the territories and asserting the power of the local lords, while serving as an administrative and economic centre for the surrounding communities.
