Cefnllys Castle

About

Cefnllys Castle (Welsh: Castell Cefn-llys, pronounced [ˈkastɛɬ kɛvn ɬɨːs]) was a medieval spur castle in Radnorshire (now part of Powys), Wales. Two successive masonry castles were built on a ridge above the River Ithon known as Castle Bank (Welsh: Craig y Castell, lit. 'castle rock') 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.

Castle Bank is often considered to be the site of an Iron Age hillfort, but there is no firm evidence to corroborate this. It has also been speculated that the princely court of a native Welsh ruler was situated nearby. The first castle at Cefnllys, 1 mile (1.6 km) north of the ridge, was a motte-and-bailey thrown up during the early stages of the Norman invasion...
