This Welsh castle was probably built in the first half of the thirteenth century, but no records exist to tell when exactly this was. The castle was built on a high rocky location overlooking the Tywi Valley and has excellent views of the land beneath. It was most likely built by a son or grandson of Rhys ap Gruffydd, also known as Lord Rhys, and formed part of the defences for the region of Deheubarth. In 1287 after meny years of peace with the English, the Welsh owner of the castle Rhys ap Maredudd took part in a revolt against English rule and the castle was besieged for a month. The castle was captured in 1403 by Owain Glyndwr and recapatured by the English. After this the castle fell into disrepair and its stone robbed for use elsewhere.
