Cleadon Mill oval enclosure

Oval enclosure, measuring 25m east to west and 13m north to south. Central depression with raised collar with stonework under the surface, suggesting a walled enclosure. Shape and proximity to Cleadon Mill Farm would suggest a pond but interior was not boggy and feature is not annotaed as containing water on the First Edition plan. Possibly a paddock or sheep stell. May date to 17th-18th century.
