The château, which was in the past the stronghold of the Coskaër de Rosanbo family, then later of the Le Peletier de Rosanbo family, is square in shape and has been developed and re-fashioned throughout its history. In the 14th Century, a fortified castle was built on a strategic headland, located 4 miles from the bay of Saint-Michel-en-Grève in order to prevent the ascent of the Bô by Scandinavian invaders. In the 15th Century, it was extended with a Gothic manor.
