 The Trécesson family is documented since the 13th century and its first known representative was the knight Jean de Trécesson, whose grandson was Constable of Brittany in the 14th century.Tradition places the construction of the site at the end of the 14th century, but it is more probable that the castle, in its present position, dates from the 15th century.At that time, around 1440, the last Trécesson heiress married Éon de Carné.
