Site Description

NAR SH39SW3

An oval earthwork enclosure set on low lying ground. Possibly a medieval castle, although it could be a prehistoric settlement enclosure.
The enclosure is about 27m north-south by 22m. It is enclosed by a rampart and ditch with a counterscarp remaining on the north-west. There is an east-facing entrance gap. The 4.0-5.0m wide ditch may originally have been a water filled moat.
