History

Probably built by Llywelyn ap Iorweth (1173-1240) towards the end of his life, the castle was partly dismantled after the English conquest, some of the timber being taken to Caernarfon for use in the royal castle there in 1284. The curtain wall and outbuildings, of which only fragmentary ruins survive, post-date the keep and may have been added by the English. The castle has been painted by many artists, including Turner.

Exterior

Castle keep. Circular plan surviving to about 14.5m in height. Regularly coursed and tightly-packed slate-stone slabs, now roofless. Original entrance on north-western side with steeply pointed arch approached by wide flight of C20 external steps; another steeply pointed arch directly above. A well-preserved lean-to garderobe tower projects to the left of the entrance and a series of narrow rectangular windows to the right indicates the position of the internal spiral staircase.

Interior

Interior is roofless; internal spiral staircase remains along with the remnants of 2 large fireplaces and empty sockets for joist and beam ends of the former floor structures.

Reasons for Listing

Listed Grade I as a well-preserved example of a C13 native Welsh castle with circular shell keep.
