Proceeding westward, the nearest castles to Cardiff were Sully and Barry, held by families from whom the manors derived their names, as did Bonvileston or Tre-Simon and its castle from Sir Simon de Bonville. Penmark was the seat of the Umfravilles; Fonmon, with its rectangular keep, of the St. Johns; Wrinston, of the De Reignys and Raleighs; Wenvoe, of Le Fleming; and St. Fagan’s, of the Le Sore family. Of Peterston and St. George’s there remain fragments of masonry. East Orchard, the seat of the Berkerolles family, and Beaupré, of the Bassets, probably were originally castles; but the one shows the ruins of a fortified house, the other of a manor-house of the sixteenth and seventeenth centuries. Part of Castleton Castle is old; of Liege Castle there remains a light earthwork only. Llandough was built by the Welsh family, and Llanquian, a round tower, by the De Wintons. Llanblethian Castle was the seat of the St. Quintins, Talavan of the Siwards: at Penlline is a part of a rectangular keep with herring-bone masonry, built by the Norrises. Cowbridge town was an appanage of the chief Lord, and was walled and strongly fortified. St. Donat’s, in its present form, is very late, and it is doubtful whether the Haweys, the early lords, had a castle in this county. Part of Dunraven is old. It was built by the Butlers, who held it under Ogmore. Ogmore, the chief seat in this lordship of the De Londres, lords of Kidwelly, has a square keep. It stands on the river whence it is named. Near it are the remains of a small castle of the Cantelupes, known as Cantelupe’s-ton or Cantleston. At Bridgend is a late Norman gateway, the entrance to a small walled enclosure, also probably Norman. It bears the name of Newcastle. Near it is Coyty, a famous Welsh seat, but built or rebuilt by the Turbervilles. The buildings are considerable and tolerably perfect. The adjacent priory of Ewenny was fortified. The Welsh Barons of Avan had a castle upon the Avon river at Aberavan.
