Coity Castle in Glamorgan, Wales is a Norman castle built by Sir Payn "the Demon" de Turberville (fl. 1126), one of the legendary Twelve Knights of Glamorgan supposed to have conquered Glamorgan under the leadership of Robert FitzHamon (d.1107), Lord of Gloucester. Now in ruins, it stands in the Community of Coity Higher near the town of Bridgend, in the County Borough of Bridgend.
