What revealed its existence was a dry summer and a satellite. On 14 July 2018, differential moisture in the soil caused the crops above buried ditches and disturbed ground to grow at slightly different rates, producing faint but readable colour variations from above. These are cropmarks, and they are one of the more quietly remarkable tools available to archaeologists working on landscapes that have been ploughed and built over for centuries.

The enclosure was identified from Google Earth Pro imagery by Jean-Charles Caillère and Simon Dowling. It is roughly rectangular, measuring approximately 30 metres on its north-northeast to south-southwest axis and around 35 metres east-southeast to west-northwest. What makes it more than a simple enclosed space is the evidence of complexity around and beyond it. There is an outer fosse, a term for a defensive or boundary ditch, running roughly 7 metres outside an inner fosse, suggesting the site was once defined by at least two concentric ditches. Adjoining the northeast quadrant is a possible annexe, a secondary enclosure measuring roughly 38 metres by 19 metres, and from the northeast angle of that annexe a further curving cropmark traces a path northward for approximately 23 metres. The picture that emerges is not of a single, simple enclosure but of a more structured compound, perhaps a settlement, a farmstead, or something with a ceremonial or defensive function, though without excavation the purpose remains genuinely open. A modern field boundary running north to south cuts through the western portion of the enclosure, and because the land on either side of that boundary carries different crops, the western section of the monument does not produce the same clear cropmark signature as the east. The site, in other words, is partially legible and partially obscured, even from space.
