Cilwhybert Motte has been described as a certain Timber Castle.

There are earthwork remains.

This site is a scheduled monument protected by law.


A moated mound, about 50m in diameter and 0.5m high, having a summit area 14m in diameter; set upon a low spur rising above the Afon Tarell valley floor: a possible adjunct of the manor house thought to have occupied the site of Cilhybert farm, as depicted on OS County series (Brecknock. XXXIII.3 1888): the house of Cilhybert is 17th century & later (see Nprn25312): OS 2nd ed. (1904) shows the moat to have been partly filled & ornamental planting upon the mound itself. (Coflein)

The monument comprises the remains of a motte and ditch, dating to the medieval period (c. 1066 -1540 AD). A motte is a large conical or pyramidal mound of soil and/or stone, usually surrounded by either a wet or dry ditch, and surmounted by a tower constructed of timber or stone. Modrydd (Old Manor Farm, Cilwhybert) is a moderate-sized motte 33m in diameter at the base and approximately 4.5m high, with steep sides and a flat summit 11m wide. The motte is surrounded by a ditch, 6m wide and 2m deep with a counterscarp on the western side. The ditch holds water on the northern and western sides. The modern farm buildings to the south of the motte are probably located on the site of the Bailey. Some small scale excavations undertaken in the past have revealed that the motte is largely made of river boulders. (Scheduling Report)

Fine motte largely made of river boulders. Possible adjunct of the manor house thought to have occupied the site of Cilhybert farm, which occupies the likely site of a bailey.

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.
