An artificial mound, 10m by 1.0-2.0m, remained after road widening in 1971, the W part of which was removed in 1973. Has been seen as an alternative site for Llanrhystyd castle, whilst thought locally to have been a mill race spoil heap. (source Os495card; SN56NW4) An alternative local tradition is that it was where the "Danes" were buried following a battle. J.Wiles 24.07.02 (Coflein at SN53716945)

The castle of Llanrhystid, called also Dinerth Castle, in 1080 belonged to Iestyn ab Gwrgan, Prince of Glamorgan, and was then sacked by Rhys, Prince of South Wales. It was destroyed in 1135, by Owain Gwynedd and his brother, aided by Hywel ab Meredydd and Rhys ab Madog ab Ednerth; and, having been re-erected, was besieged and taken, in the year 1150, with several other fortresses, by Cadell, Meredydd, and Rhys, the sons of Grufydd ab Rhys, Prince of South Wales, who, enraged at the spirited resistance of its defenders, whereby they lost some of their bravest troops, put the garrison to the sword. It was fortified by Roger, Earl of Clare, in 1158, and, about the close of the same century, was besieged and taken by Maelgwyn ab Rhys, who slew the garrison left to defend it by his brother Grufydd, and in 1204 razed it, with several others, to prevent its falling into the hands of Llewelyn ab Iorwerth.
