Once the home of William Randolph Hearst and his Hollywood guests, the 12th century castle is now home to Atlantic College.
It contains over 800 years of history including antique ceilings, fireplaces, a moat, battlements, dungeons and even a witch called Mally-y-Nos. Standing within beautiful tiered gardens it enjoys spectacular views to the Bristol Channel.
One of the Vale of Glamorgan's biggest festivals, 'Beyond the Border', is hosted in the grounds of St Donats Castle every other year. St Donats is a popular venue for weddings.
It is also home to St Donats Art Centre with its varied programme of events.
Castle Tours are available at selected days.
