Cefn Barn Ringwork, Trefeca Fawr has been described as a probable Timber Castle, and also as a probable Masonry Castle.

There are masonry footings remains.

This site is a scheduled monument protected by law.


A sub-circular enclosure, c.24m by 21m, defined by a bank and ditch, with an entrance to the E. Suggested identification as "castellum Waynardi" (mentioned 1143-55). (Coflein)

The monument comprises the remains of a well preserved castle-ringwork, which dates to the early part of the medieval period (c. AD 1066 - 1485). The ringwork is roughly circular in plan, measuring 27m N/S and 23m E/W with a discontinuous bank and ditch defining the outer edge of the enclosure. The interior is flat. The bank is steep sided, a maximum of 1m high on the inside and 2.2m high on the outside, and surrounded by a shallow ditch, 0.3m to 0.5m deep. The ditch is intermittent and does not survive on the S or E sides. There is a gap in the bank on the E side which may be the original entrance. At the W end of the site is a stone outcrop at the foot of the bank which is around 3m high. A hollow to the S of the outcrop may be the result of quarrying. (Scheduling Report)

It is suggested that possibly the ringbank is rubble remains of masonry enclosure wall. Salter identified this as a predecessor or siege-camp. No real reason to think it was a predecessor site. The location, on a hillside, has some value as a siege work but would be vulnerable to counter attack but there is no history of a siege and a siege of such length as to make building such a fortification worthwhile would probably be recorded. Possibly an Iron Age farmstead with drystone enclosure wall but does seem to be well accepted as medieval by the usual authorities.
Waynard's Castle is an unidentified castle mentioned in mid C12 Charter, near Talgarth, identified as possible Trefecca Fawr by Remfry and as either Trefeca, Trefeca fawr or, most favoured, Garn y Castell by King.

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.
