St Donats uk/local/swansea/castle/">Castle in Wales originated as a late 12th-century medieval fortress built near the coastline of the Vale of Glamorgan. The site evolved from an early timber defensive structure into a stone fortification under Norman noble family influence.
The land original ownership belonged to the de Hawey family before passing through marriage to Sir Peter Stradling in the late 13th century. The Stradling family retained ownership of St Donats Castle for four centuries. Sir Edward Stradling expanded the living quarters and established formal terraced gardens during the Tudor era. The direct Stradling lineage ended in 1738 following the death of Sir Thomas Stradling in a duel. The estate suffered decades of structural neglect through distant ownership until restoration efforts began in the late 19th century. American publishing magnate William Randolph Hearst purchased the property in 1925. Hearst invested substantial capital to import historic wooden ceilings and stone fireplaces from continental Europe. French businessman Antonin Besse bought the property in 1960 and donated the site. The castle became the foundational campus for United World College of the Atlantic in 1962.

The exterior terraced gardens drop in six distinct levels toward the coastal sea wall.
