Description
NAR SH50SE11

An oval ridgetop enclosure, about 80m north-east to south-west by 36m, with an annex extending a further 24m to the north-east. The main enclosure is defined mostly by scarps above natural slopes. A rampart runs about the west and south sides, with a ditch and counterscarp on the west covering both enclosure & annex. There is a possible east-facing entrance.
Monuments such as this are generally assigned an Iron Age date, although many were maintained and some founded anew, across and beyond the Roman period.
