The site of the castle was the location for several earlier buildings, the first of which is said to have been built by Arnold Le Boteler (Butler) in the mid-12th century. By the 16th century, a manor house owned by the Vaughan family stood on the site, its existence recorded by John Leland.
In 1642 the mansion was sold to the Wyndham family. Thomas Wyndham of Dunraven was MP for Glamorgan from 1789 to his death in 1814. The estate then passed to his daughter Caroline, who in 1810 had married the Irishman Windham Henry Quin (1782–1850), later 2nd Earl of Dunraven; in 1815 he assumed the additional name of Wyndham in right of his wife, becoming Windham Wyndham-Quin. It was inherited by Edwin Wyndham-Quin, 3rd Earl of Dunraven and Mount-Earl, MP for Glamorganshire 1837-1851, and descendants. It was lived in until after the Second World War, having been used as a military hospital.
The castle's walled garden survives and is in the care of the Vale of Glamorgan Council.
