Rumney Castle has been described as a certain Timber Castle, and also as a certain Masonry Castle.

There are earthwork remains.

This site has been descheduled.


The earthwork remains of Rumney Castle were excavated in 1978 and de-scheduled in 1986 due to planned development on the site. (Coflein)

The castle was a motte placed on the edge of the fall to the river. Only part of the mound survives in a garden, but it is the greater part and it retains much of its formidable ditch. The motte was fairly low but extraordinarily broad-topped, its summit having originally had a diameter approaching 100ft. Excavation at Cae Castell in 1978 and 1980 showed that the site was first fortified by a ditch and bank forming a ringwork. (Glamorgan-Gwent Archaeological Trust HER)

Small ringwork historically part of the marcher lordship of Gwynllwg, was situated above a steep natural scarp overlooking the river Rhymney. First mentioned in A.D. 1184-85, the castle guarded the western boundary of the lordship and the river crossing. The defenses consisted of a ditch and clay rampart constructed around three sides of the site. Initially incorporated into the defenses along the fourth side was a large timber building and possibly a palisade. The entrance was originally defended by a large timber gate tower, later superseded by a smaller timber structure. Following this, the defences were strengthened by the widening of the rampart and the construction of a small tower or keep alongside the entrance. Several phases of timber building, including two large halls, were arranged around a courtyard. During a later period the entrance was relocated and a stone gate tower constructed. (Lightfoot)

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.
