It does not announce itself in any way. There is no marker, no hollow in the ground, no visible trace. The only record of it is a ghostly ring preserved in a single aerial photograph, where the buried feature caused crops growing above it to ripen differently from the surrounding field, making the circular form briefly legible from the air before the land changed hands and the moment passed.

A ring-ditch of this kind is typically the ploughed-down remnant of a burial mound, the surrounding ditch all that survives after centuries of tillage have gradually levelled whatever once stood at the centre. The photograph, taken on 13 July 1989, captured the cropmark clearly enough to confirm a roughly circular form before the Ashfield housing estate was subsequently built across the site. The field had previously been in tillage, and the ground beside a river that flows southward into the Nore some 270 metres to the east would have been well-suited to agriculture. About 200 metres to the south-east, a further cropmark showing an enclosure was identified around the same time, and this feature may be connected to a relic field system in the wider area, suggesting the landscape here carried traces of organised activity long before the city expanded to absorb it.
