🏰 Cefnllys Castle

Cefnllys Castle was a medieval spur castle in Radnorshire, Wales. Two successive masonry castles were built on a ridge above the River Ithon known as Castle Bank in the thirteenth century, replacing a wooden motte-and-bailey castle constructed by the Normans nearby. Controlling several communication routes into the highlands of Mid Wales, the castles were strategically important within the Welsh Marches during the High Middle Ages. As the seat of the fiercely contested lordship and cantref of Maelienydd, Cefnllys became a source of friction between Llywelyn ap Gruffudd and Roger Mortimer in the prelude to Edward I's conquest of Wales (1277–1283). Cefnllys was also the site of a borough and medieval town.
