St Donat's Castle

St Donat's Castle is a medieval castle in the Vale of Glamorgan, Wales, overlooking the Bristol Channel in the village of St Donat's near Llantwit Major, and about 25 km west of Cardiff. Since 1962 the castle has housed the international Sixth form college Atlantic College.

The castle lies on an elevation to the east of a small valley opening to the sea between precipitous sea cliffs to both east and west.

An inner court about 40m across within a polygonal inner curtain wall is closely surrounded by an outer court and curtain wall with a dry moat facing the eastern approach. The curtain walls date from c.1300, having been built by the first Stradling (or perhaps by his widow's second husband). The outer wall mostly survives and has a small original tower entirely contained with it on the north, and a square gatehouse on the east. The inner court is entered by an arch on the east side beside the rectangular Mansell Tower (an enlargement of the original keep). The north-western range is of the early 16th century; the north-eastern range is of the late 15th century; the late 15th century Great Hall is on the south side of the court.

Beside it, squeezed in between the inner and outer curtain walls, is the Bradenstoke Hall, consisting of the inner curtain wall on the north side, the somewhat realigned outer curtain wall on the south, with a modern wall on the east end built at the point so that an early 14th century roof (brought from Bradenstoke Abbey in Wiltshire) would¨fit. The western range has been largely replaced by a much larger three-storey building (which necessitated, when erected, the demolition of the western part of the outer curtain wall). Its ground floor is a large modern dining hall with a very fine 15th century roof, probably Flemish in origin but imported from Boston Stump Church (Lincolnshire). The Lady Anne tower on the south-western corner of the castle has been rebuilt many times.
