A roughly oval, somewhat polygonal, enclosure, about 70m north-east to slouth-west by 42m. It is defined by a ruinous stone wall, about 2.7-3.0m across. The only entrance faces north-east and is flanked by an additional ditched mound on the north side.
Monuments such as this are generally assigned to the Iron Age, although many were maintained and some established anew, throughout and beyond the Roman period.
