St Donat's Castle (Welsh: Castell Sain Dunwyd) is a medieval castle that has, since 1962, housed an international secondary school called Atlantic College. The earliest surviving parts of the castle (the keep and what is now the inner curtain wall) were built in the late 12th century by the de Hawey family. Ownership passed to the Stradling family in 1298, who built the outer gatehouse and curtain wall around 1300, and constructed the inner court around 200 years later.

 

The castle is reputedly haunted by Lady Anne Stradling, who's husband died in the Crusades. Her ghost was said to appear as a death omen for the family. The Welsh equivilent of the Banshee - the Gwrach-y-rhibyn - has also been reported here on the night before a Stradling died She would be accompanied by a pack of black dogs with wild red eyes.

 

In the 19th century, the castle was troubled by various paranormal phenomena, including that of a ghosty black panther in the corridors; a bright light akin to a "glaring eye"; a hag in the library; and the piano would be played by unseen eyes. An exorcism was duly conducted which seemed to deal with the issues.
