Ruin of the C13 hall of a medieval residence of the Bishops of St Davids recorded from the C12. Llanddew Castle was occupied in the C12 by Giraldus Cambrensis, as Archdeacon of Brecon 1175-1203. He called it 'a small residence. .... well adapted to literary pursuits and the contemplation of eternity'. Archbishop Baldwin of Canterbury stayed at Llanddew on his tour of Wales with Giraldus in 1188. The castle was derelict by the C16. Sold in the 1650s, but returned to the see of St Davids after the Restoration. In the 1741 Buck engraving the front wall, now entirely gone is shown standing and much more survived of the back wall. Restored in 2003 when a cushion shaped corbel was found in the top corner.
