This mound stands in the centre of the village of Castlebythe, a few yards from the parish church. The Ordnance sheet styles it a " Tumulus," and marks another monument adjoining it as "Castell y Fuwch." It is, however, an unmistakable mound castle, the adjacent Castell y Fuwch being the bailey. The mound has been much disturbed, whereby its appearance has been altered. Its height varies from 10 feet to 20 feet, and its summit diameter is about 40 feet. It was surrounded by a ditch which is much filled up. The bailey is an oval measuring 220 feet by 170 feet; its encircling bank has a height of 12 feet from the bottom of the ditch. There is a strong spring just within the north bank. Lieut.-Col. W. LI. Morgan, R.E., an ex-Commissioner, was informed in 1870 of "a further enclosure to the north-east, slightly longer than this detached bailey. About half of it was destroyed by the making of the railway." This second enclosure has almost entirely disappeared. (RCAHMW)

An apparently isolated and disturbed motte, 4.2m high. (Coflein)

Gatehouse Comments

A Cas Fuwch enclosure 300m west cannot be the lost Castell y Fuwch bailey. The railway has also now disappeared and the removal of the railway is likely to have destroyed whatever archaeology was left.
