History Of Sully

Sully Island has evidence of an Iron-age fort and the village is thought to go back to Roman and Saxon times. Certainly the village came to the fore, when Reginald de Sully, who came over with William the Conqueror and was one of the 12 Knights of Glamorgan, built a Castle to guard the tidal estuary between Sully and what is now Barry.

More recently, the world’s first successful heart-transplant (on a chimpanzee) took place at Sully Hospital.
