The castle stands on a low cliff by the side of the Coran stream, overlooking the estuary of the river Taf. Laugharne may be the castle mentioned in about 1116 as the castle of Robert Courtemain, but the first definite reference to the Norman castle is in 1189 when, after the death of King Henry II, it was seized by the Lord Rhys, prince of Deheubarth. It attracted further hostility from the Welsh in 1215 when it was destroyed by Llywelyn the Great and later, in 1257, when it was again taken and burnt.
