Castell Moeddyn Fach, Llanarth has been described as a Timber Castle although is doubtful that it was such.

There are earthwork remains.

This site is a scheduled monument protected by law.


The tapering, sloping end of a south-facing promontory, 48m deep, is cut off by a roughly 22m east-west bank and ditch, having a central entrance. (Coflein)

A small promontory site defended on the east and west by streep natural slopes and by a bank and ditch to the north. The defences are c.13m wide and 2m high overall with a central causewayed entrance. JH 1995 based on Cadw 1987 & CCH 1994 (Dyfed Archaeological Trust HER)

The monument comprises the remains of a defended enclosure, which probably dates to the Iron Age period (c. 800 BC - AD 74, the Roman conquest of Wales). Inland promontory forts are usually located on a ridge or spur with steep slopes on 2 or 3 sides, and artificial ramparts on the level approaches. Alternatively they may have been constructed on a promontory above the confluence of two rivers, or in the bend of a meander. This monument is a small promontory fort, consisting of a triangular shaped piece of ground with steep slopes down to rivers on the south, west and east; the neck on the north is defended by a curving bank c.1.8m high internally, 2.5m externally above the bottom of a well-preserved 5m-wide U-shaped ditch. On the north side of the ditch is a field boundary which may incorporate a counterscarp bank. In the centre of the bank is an entrance with a causeway over the ditch. (Scheduling Report)

Hogg and King recorded this as a 'possible' medieval castle, which in their terms meant unlikely. The position is fairly isolated. The site is scheduled as a prehistoric enclosure and this seems a more likely identification. This has been identified as a possible location for Castell Mabwinion mentioned in 1165 and 1216.

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.
