Across the car park from the heritage centre rises the shattered ruin of the motte-and-bailey Llandovery Castle, which wasbuilt in 1116. The castle changed hands many times between the Normans and the Welsh, and between one Welsh prince and another, taking a severe beating in the process; it was finally left to decay after Owain Glyndŵr had a go at it in 1403. It's fronted by an eerie disembodied stainless-steel statue commemorating Llewellyn ap Gruffydd Fychan, who was gruesomely hung, drawn and quartered by Henry IV for refusing to lead him to Owain Glyndŵr's base.
