There is nothing to see when you stand in the field itself; the circle exists as a cropmark, a faint difference in the way grass or grain grows above buried archaeology, revealing the ghost of a fosse, a defensive ditch, that was dug and eventually filled in so long ago that the soil has closed over it entirely.

Aerial photography taken in July 2000 caught this circular enclosure in the right conditions, when differential crop growth made the line of the old ditch legible from above. That same survey also picked up a second, larger enclosure nearby, and the relationship between the two is what makes the site quietly interesting. The larger enclosure appears to be the older of the pair, and the smaller one was laid out in a position that slightly overlaps it, cutting into its north-eastern quadrant. This kind of stratigraphic layering, where one settlement or enclosure is imposed upon the edge of an earlier one, suggests the spot was returned to and reused across different periods, though exactly when remains unknown without excavation.
