You cannot see it from a road, or from a nearby hill, or through any conventional aerial photography. It reveals itself only through a cropmark, the faint differential in how vegetation grows over buried soil disturbance, and only when viewed through Google Earth imagery captured on a specific July day in 2018.

The feature is a ring-ditch, a type of monument defined by a continuous fosse, or ditch, running in a closed circle. Ring-ditches are generally understood to be the eroded remnants of prehistoric burial or ritual enclosures, the ditches having once surrounded a central mound that has long since been ploughed flat. This particular example sits on a south-east-facing slope, in what appears to be a slight fold in the land on a natural shelf of ground, a position that may have held some significance to whoever constructed it, or that may simply reflect where the geology allowed for easier digging. It was first reported by Simon Dowling, whose scrutiny of satellite imagery brought a feature invisible at ground level into the archaeological record.
