What is recorded here

Deganwy Castle stands as a circle of grassy mounds on a volcanic plug, marking the spot where wooden towers, stone walls and deliberate demolitions collided for centuries. Llywelyn ab Iorwerth refortified it after recovering it from the Earl of Chester, while Dafydd ap Llywelyn destroyed it before an English advance, and Henry III later spent more than £2,200 rebuilding what Welsh princes kept breaking. The hill still holds the shape of that argument: a small castle repeatedly made strong, seized, ruined and remembered at the mouth of the Conwy.

The National Monuments Record of Wales records Deganwy Castle as Castle from the Medieval period. The saved point comes from the official national record. Inclusion does not by itself mean that the public may enter the place.

Deganwy Castle was built by the Normans in the late 13th century, likely under the direction of Gilbert de Clare, following the conquest of North Wales. It is important as a strategic military site and as an example of early medieval castle architecture in Wales.
