Building of the castle was first begun by
Gilbert de Clare, 3rd Earl of Gloucester on land claimed by
Humphrey de Bohun, 3rd Earl of Hereford. Warfare broke out between the Earls in 1290 and they were severely admonished and fined by King
Edward I of England, who had to march down from
North Wales to intervene. The castle was captured by
Madog ap Llywelyn in 1294. The castle is believed to have never been fully completed, and the location was too remote and exposed to serve as a residence. The Bucks' engraving of 1741, however, shows that fragments of the walls then still stood high. ==Description==
