This site has been considered by some writers to be a castle but is rejected as such by Spurgeon as natural outcrop. Recorded by Clwyd Powys Archaeological Trust as Non Antiquity and in RCAHMW as 'almost certainly natural'.
Neuadd Wèn, now a farmhouse, was anciently the mansion of Meredydd ab Cynan ab Owain Gwynedd, Prince of Wales, and appears, from the few remains of the old building which have been found among some rubbish at the back of the present house, to have been erected about the eleventh or twelfth century: among these vestiges were the ruins of an arched window, with mouldings of freestone, in the style of that age. This mansion was once called Llys Wgan, from a rivulet near the spot; and adjoining it is the farm of Llysyn, also at one time a family seat, and which appears to have derived its name, a diminutive of Llys, "a palace," from its vicinity to the first-named residence.
