[3][5] Carreghofa Castle was built in 1101 by Robert de Bellême in the North Wales border regions, without the permission of the newly crowned King Henry I.

This was a politically tumultuous region in the medieval Kingdom of Powys, founded in the 5th century, which began experiencing increased threats from the east following the Norman Conquest of England in 1066.

[6][7] In building Carreghofa Castle, de Bellême was directly allying himself with the princes of Powys, the sons of Bleddyn ap Cynfyn, against the English monarchy.

[3] A decade later in 1197, Gwenwynwyn, the second ruler of the southern Powys region, was voluntarily given ownership of the castle by the English in exchange for surrendering Rhys ap Gruffudd to them.

[5] Carreghofa Castle is believed to have been destroyed a final time in the 1230s (approximately 1236) as part of Llewelyn ap Iorwerth’s campaigns against English rule in Wales.
