Le château en bref
At the locality of Le Plessis, in the commune of Mauron, on the edge of the Forest of Paimpont, the château du Plessis, or Plessis-Mauron, is the former seat of a lordship and then a barony, of which almost nothing remains. The lordship is recorded as early as 1190, when it belonged to Guillaume I, sire du Plessis, ancestor of a line of ancient Breton chivalry, the du Plessis-Mauron family. In 1592, the marriage of Jeanne du Plessis-Mauron passed the estate to the Bréhant family, and the lordship was raised to a barony in 1655. According to the Société d'histoire de Brocéliande, it then passed to the d'Andigné, d'Harcourt, Nicolay, Rougé and Miramont families. The medieval castle was replaced in the 18th century by a vast complex comprising a large main building and four pavilions at the corners of the courtyard, with outbuildings and a small 16th-century turret. Converted into a farmstead (métairie) in the 19th century, it deteriorated rapidly, as observed in 1884, and then disappeared. Today only a 17th-century private chapel survives, on private land.
