Allt y Ferin, Llanegwad has been described as a certain Timber Castle.

There are earthwork remains.

This site is a scheduled monument protected by law.


The earthworks at Allt y Fern are thought to represent a medieval motte and bailey castle superimposed upon an earlier promontory enclosure: the motte is a near-circular steep-sided mound, 27-8m in diameter & rising 6.0m to an 9.0-10m diameter summit, ditched about on all sides; it is inset into the eastern angle of a subrectangular enclosure some 52m north-east to south-west, having a north-east facing rampart & ditch beyond which a further roughly 84m sweep of rampart and ditch covers both motte and bailey from the level ground on this side; the remainder of the enclosure is defined by scarps above steep natural slopes, a 25m section of ditch cutting off the 50m tail of the promontory: OS County series (Carmarthen. XXXII.15 1889) appears to show a 9.0m diameter circular structure set upon the summit of the mound, which is surrounded by a 25m diameter boundary, apparently set at the base of the ditch: these last features may be associated with Plas Alltyferin (Nprn120788). (Coflein)

The monument comprises the remains of a motte and bailey castle, a military stronghold built during the medieval period .The motte measures c 28m in diameter at the base and rises c 6m in height to a summit of c 10m diameter. A summer house associated with the nearby mansion Plas Alltyferin formerly stood on the summit. The motte has a surrounding narrow ditch with a 2m counterscarp bank and is set into the eastern angle of a subrectangular bailey that measures c 52m north-east to south-west defined by steep natural scarps except on the north east where a rampart & ditch 3m high on the exterior, 1m high on the interior re-uses the earthworks of an earlier prehistoric promontory enclosure. A second slighter ditch and bank measuring c 25m in length cuts off the tip of the promontory. (Scheduling Report)

Has been identified as 'Dinweiler' taken by the Welsh and recaptured in 1159.
