No earthwork survives at ground level; what remains of it exists only as a ghostly outline pressed into the soil, readable solely from the air. That is how it was discovered, captured in an aerial photograph taken on 13 July 1989, which revealed a cropmark tracing the outline of a roughly square enclosure measuring approximately 25 metres on each side.

Cropmarks appear when buried features, such as the filled-in ditch of a former boundary, affect how crops or grass grow above them. A fosse, essentially a defensive or boundary ditch dug into the earth and later silted over, retains moisture differently from the surrounding undisturbed soil, and in dry summers the variation in growth becomes visible from above. The 1989 photograph showed just such a pattern here, the rectilinear shape of the fosse emerging against the crop in a way that centuries of ploughing and grazing had otherwise erased. The enclosure sits on a ridge with the River Nore running roughly 200 metres to the south-west, a position that would have offered both prospect and proximity to water, practical advantages in any period. Immediately to the south-east lies a second, curvilinear enclosure, the two sites forming a pairing that raises obvious questions about their relationship and relative age, questions the available evidence does not yet answer.
