Danylan Mound, Llyswen has been described as a Timber Castle although is doubtful that it was such, and also as a Palace although is doubtful that it was such.

There are earthwork remains.

This site is a scheduled monument protected by law.


A mound, 22m in diameter and 1.0-4.0m high, upon a spur-end: interpretations range from barrow, through motte, to ornamental tree-ring. (Coflein–ref. J.Wiles 19.08.02)

The monument comprises the remains of a earthen built round barrow, which probably date to the Bronze Age (c. 2300 - 800 BC). The barrow is circular in shape and has a rounded profile. It is located on a slope of hillside and is about 5 ft high with no visible ditch. (Scheduling Report)

Rejected by King as a natural hillock. Scheduled as Prehistoric Round Barrow, otherwise recorded as mound of unknown or modern date. Remfry argues that this is a medieval welsh castle, a successor to a Dark Ages welsh llys site (recorded as a Iron Age hillfort.) This suggestion is not taken up by others but the location, near a spring and well, is not improbable although a site adjacent to the parish church might be more likely, although the link between church and llys is not as strong as the link between church and thengal burh in Saxon England. Presumably the early llys site was abandoned for the better water supply. The mound is quite small but the whole site is of a reasonable size. Is this a symbolic mound built in imitation of a Norman motte by a welsh lord but without a ditch? A site worthy of reconsideration and investigation but, although may well be medieval, probably can not be considered to be fortified and, therefore, not a castle.

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.
The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown.
Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
