Earthworks representing a much mutilated & abused medieval motte & bailey castle, occupying a pronounced south-east facing spur: the remains of the motte, largely removed by 1976, are currently about 34m in diameter & up to 3.4m high; OS County series (Carmarthen. XV.13 1889) depicts the mound, previously some 4.5m high, as having a rather rounded triangular summit area, about 25m north-west to south-east by 20m; traces of ditching have been observed about the motte, which occupies the southern end of a subrectangular scarped enclosure, some 88m north-east to south-west by 55m; this enclosure circuit is rounded about the motte, suggesting a counterscarp, there being space for a near rectangular bailey, some 40m by 30m, facing rising ground to the north-east: it may be presumed that the castle was abandoned by the time that Gwyddgrug became a grange of Talley Abbey.

Nothing much now remains of this motte and bailey castle, as much of the site has been robbed for gravel, for farm track repairs. (Dyfed Archaeological Trust HER)
