UWC Atlantic is an independent boarding school in the Vale of Glamorgan in south Wales. Founded in 1962, it was the first of the United World Colleges and was among the first educational institutions in the world to follow an international curriculum; it helped create the International Baccalaureate Diploma Programme in the 1960s.

St Donat's Castle, St Donats, Wales, is a medieval castle in the Vale of Glamorgan, about 16 miles (26 km) to the west of Cardiff, and about 1+1⁄2 miles (2.4 km) to the west of Llantwit Major. 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.
