Mainly 12th - 15th centuries. The castle is set in lush green surroundings on a rocky spur that faces out to the sea. The castle ruins were acquired by the Côtes d'Armor regional council in 1981. With little historical information to go on, the castle's past is still uncertain. Only archaeological research can offer some reliable information on how and when it was built. Programmed digs are therefore organised every year, under the direction of an archaeologist from the Regional Archaeology Department.
