Visiting St Donats Castle

St Donats Castle is in Llantwit Major in the Vale of Glamorgan. Not many people know about it because it is a real-life Hogwarts. Most of the year, it is a school and a wedding venue at the weekend and during the summer. However, you can visit to tour the castle or attend one of the many events.

St Donats Castle Tours

One of the most asked questions is can you visit St Donats Castle? Is St Donats Castle open to the public? Yes, it is, but not all of the time. On selected dates, the castle opens its doors so all visitors can see the antique ceilings, fireplaces, battlements and dungeons.

It is also a filming location. So you may recognise it from A Discovery of Witches, Wolf Hall, Doctor Who, Da Vinci’s Demons or The Hollow Crown. 

Our tour took over two hours and was packed with interesting information on the history and building.

St Donats Castle History

The site has been occupied since the Iron Age and was the home of the Celtic chieftain Caradog. The de Haweys family initially held St Donats. The heiress married Sir Peter de Stratelynge (Stradling). The Stradling family occupied the house from 1289 until the late 1730s. In the late 14th Century, Edward Stradling was twice Sheriff of Glamorgan and his wife inherited nearby Coity Castle. Their grandson married a daughter of Henry VI’s great uncle Cardinal Beaufort and became Chamberlain of South Wales.

King James I made John Stradling a baronet in 1611, despite the family having remained faithful to the Roman church during the Reformation. They fought for King Charles I during the Civil War and were even a leader of the Royalist force at the battle of St Fagans.

The estate passed to a cousin named Bussey in 1738, ending the time of the Stradling’s. Upon his death, the estate was divided, and the heirs neglected the castle until 1862. It was bought by Dr Nicholl-Carne, a descendent of the Stradling’s. He began its restoration.

More recently

In 1901 it was sold to Morgan Stuart Williams, a coal mine owner, who did further work on the castle. In 1922, Richard Pennoyer bought the castle but sold it to a fellow American in 1925, the millionaire William Randolph Hearst. Extensive and not always sensitive changes were made between 1925 and 1937. During this time, Hollywood stars would holiday here. Such as blonde bombshell Marion Davies, Charlie Chaplin, Constance Talmadge and a young John F Kennedy.

The caste was put up for sale and remained unsold until 1960. However, it was used for training army officers during the second world war. It became the site of Atlantic College in 1962. Who owns St Donats Castle? The castle is owned by Antonin Besse II, who donated it to the founding council of Atlantic College. The idea for an international school arose from his meeting with Kurt Hahn. 

St Donat’s Castle School

Atlantic College St Donats Castle has 350 students from more than 90 countries living in houses on the grounds. Their studies are for two years. Known as the UWC Atlantic Experience, the college aims to educate and unite people, nations and cultures.  

Students stay in four-person dorms with people from different backgrounds, helping them be more culturally aware and to become respectful of values and beliefs. They have modern bathrooms, study areas, day rooms and kitchens. When I visited, more dormitory buildings were being erected.

Alongside their studies are exciting social groups like Cine Club, Choir and dance. Hot To Go is a student-run professional restaurant with a head chef, sous chefs and waiters. Each Saturday, the Moondance Café transforms into a restaurant with table bookings so that you can meet your friends. All profits are reinvested into kitchen equipment.
