Royal Commission aerial reconnaissance on 4th July 2018 identified a circular enclosure measuring c. 56m diameter, lying to the north of Castellior. The enclosure is open on the north side, and features a broad inner ditch with a very narrow outer ditch which is possibly a palisade trench. There is a possible pit in the southern part of the enclosure. The enclosure lies to the south of a rectangular enclosure or cursus discovered on the same flight.

Discovered during the 2018 drought.
