St Donat's Castle is a medieval castle in the Vale of Glamorgan, positioned on cliffs overlooking the Bristol Channel. The site has been occupied since the Iron Age, and was by tradition the home of the Celtic chieftain Caradog. The present castle's origins date from the 12th century when the de Haweys and later Peter de Stradling began its development. The Stradlings held the castle for four hundred years, until the death of Sir Thomas Stradling in a duel in 1738.
During the 18th century, the castle's status and condition declined and by the early 19th century it was only partly habitable. The later 19th and early 20th centuries saw several restorations.
Today the castle is home to some three hundred and fifty international students and, with a history of occupation extending back to the late-13th century, is among the oldest continuously inhabited castles in Wales. Both the castle and the grounds are of historical and architectural importance, and have Grade I listed status.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
