Kenfig Castle was erected in the mid-12th century by Robert, Earl of Gloucester, as an important Norman administrative and defense center, and by 1183 a borough was built next to it. Kenfig was plundered by the Welsh at least 6 times: in 1167, 1183, 1232, 1242, 1294 and in 1295 by Morgan Ap Maredudd, during the rebellion of Madog ap Llywelyn, and also in 1316 during the revolt of Llywelyn Bren. At the beginning of the fourteenth century, the castle was thoroughly rebuilt and strengthened, but at the end of the fifteenth century, both the Kenfig town and the castle were abandoned due to sand dunes covering both these centers. In the sixteenth century, the castle was already in ruin.
The castle consisted of a quadrilateral keep with a side length of 14 meters, erected on an artificial earth mound. The corners of the tower’s base were reinforced with buttresses or rather spurs. The entrance was from the south-west side, also from this side there was an outer bailey, surrounded by a moat and an earth rampart. At the beginning of the fourteenth century, a stone, perimeter defensive wall was erected with a large gatehouse, leading from the outer bailey to the castle’s settlement.
The castle has not survived to the present day, only relics of the keep are visible.
