Restormel Castle is situated on the River Fowey. It was built in 1100 in the typical motte and bailey style and is a perfect excample of military architecture of its period, and one of the finest in England. The castle belonged to the Cardinhams in the twelfth century, until Andrew de Cardinham's daughter married Thomas de Tracey, who owned the castle in 1264, after which it went to Simon de Montfort and to Henry III's brother, Richard of Cornwall. Richard died in 1271, and his son Edmond in 1300. Subsequently it has always been the property of the Duchy of Cornwall.
