Origin and history

Kerat Manor, located in Arradon, Morbihan, is a defensive building built in granite in the 15th century on the foundations of a first building of the 10th century. Organized in three bodies of "U" buildings around a central courtyard, it included a common room of 50 m2, a kitchen, a pantry and two screw stairs leading to the bedrooms. Its 100 bolt holes (pigeon tree) indicated a seigneury of about 100 hectares, one of the largest in Vannetese. The facade features a curved door and carved fireplaces, typical of the Breton architecture of the time.

The mansion was erected at the end of the 14th century by Lord Redoret as a defensive residence controlling the Arradon Point and access to the island of the Monks. In 1480 he passed to the family of Arradon through the marriage of Perrine Redoret with Jean d'Arradon, uniting the seigneuries of Kerat and Kerran. Turned into a farmhouse, it remained a farm until 1975, the date of its first restoration. The facades and roofs were classified as historical monuments in 1974. Private property since 2004, it illustrates the evolution of the Breton seigneuries between military and agricultural use.

The estate, accessible by a guard house called "the Fisherman's House", includes stables and a longère (old stable) perpendicular to the mansion, opening onto the Gulf of Morbihan. The skylights, redone in the seventeenth century, and symmetrical staircases reflect architectural adaptations over the centuries. The site, located 1 km south of St Peter's Church in Arradon, bears witness to the strategic importance of coastal manors in controlling sea lanes and farmland in medieval Brittany.
