NAR: SN90SE1

The SE end of an isolated eminence 35m (N-S) by 12m, an entirely natural hillock, rocky except for the small oval flat top which has been scarped and ditched on the N and W. Traces of a possible bailey lie to the NW.
There is no historical record of the motte which is possibly a medieval Welsh attempt to construct a motte-like fortress from this naturally strong position.
