The site of an Iron Age Roundhouse or defended enclosure. It survives as a grass covered earthwork, set in a marshy area. Its siting and general construction is comparable to the earth built Roundhouses of about 200 AD. It consists of an oval raised area which measures 25.0 metres east to west and slightly larger north to south. It is raised approximately 0.7 metres above the surrounding ground surface. It has an outer ditch with an outer bank visible to its north side but this is not apparent in the remaining quarters of the monument. No entrance has been identified.
