The circular enclosure here has never been excavated or formally mapped at ground level; what we know of it comes from a single aerial photograph taken in July 1989, in which the outline of a fosse, the defensive ditch surrounding an enclosure, showed up as a cropmark in the soil below. Cropmarks form when buried ditches or banks affect how overlying vegetation grows, producing subtle differences in colour or height that are invisible on foot but legible from the air in the right light and season. That brief window of visibility revealed a roughly circular enclosure approximately thirty metres in diameter.

What makes the photograph particularly interesting is not just the enclosure itself but what surrounds it. Linear cropmarks were recorded immediately to the east, south, and west, suggesting the presence of boundaries or features that may have organised the surrounding land. About seventy metres to the south-east sits a possible second enclosure, and roughly a hundred and twenty metres further south lies a ring-ditch, a type of feature often associated with prehistoric burial or ceremonial activity. The whole cluster falls within a wider field system, meaning this was not an isolated structure but something embedded in a working or inhabited landscape. Whether that landscape was prehistoric, early medieval, or some layered combination of both, the aerial evidence alone cannot say.
