Dunraven Castle is a ruined castellated mansion perched on the Glamorgan Heritage Coast cliffs near Southerndown, Bridgend, overlooking the Bristol Channel. The site's fortification history spans from the mid-12th century, but the current structure originated as a manor house remodeled into a hunting lodge by Thomas Wyndham in 1802–1806. Caroline Wyndham undertook significant remodeling from 1858, replacing the central tower with a conservatory and enlarging the wings. The house served as a military hospital during the Second World War and was demolished in 1963, leaving evocative clifftop ruins. The surviving walled garden, gatehouse, and other structures are freely accessible as part of the Glamorgan Heritage Coast, with seasonal parking available.
