Caergwrle Castle was erected by Dafydd ap Gruffydd in about 1278, and was thus the last native Welsh stone built castle. The remains of the late thirteenth century masonry castle are set at the south-south-west angle of an irregular enclosure defining the relatively level summit of a steep-sided hill. Excavation demonstrated that this enclosure, roughly 110m north-west to south-east by 120m, had been defined by a stone-revetted wall, radio-carbon dating indicating an early medieval date.
