The only way it becomes legible is from above, through the medium of a satellite image captured on a single June day in 2018, when the growing crops above the buried remains responded differently to the soil beneath them, producing a faint arc in the tillage that gives away a structure long since swallowed by the landscape. Cropmarks of this kind form because buried ditches and banks alter the moisture and nutrient content of the soil above them, causing crops to grow taller or shorter, greener or paler, in patterns that trace the outline of whatever lies underneath.

The arc that emerged in that imagery measures roughly 37 metres across the chord, with a height of about 15 metres, suggesting a substantial circular feature. Its fosse, the surrounding ditch typical of early medieval enclosures, is traceable from the west-south-west around through north to the north-east. The southern portion of the circle appears to have been cut away by two roads that cross near its centre, one running north-west to south-east and another running north-east to south-west. By the time the first edition Ordnance Survey map was made in 1839, a small quarry had already been dug at the junction of those two roads, sitting within what would have been the enclosure's interior, suggesting that whatever physical trace remained above ground had already been heavily disturbed by then. The site was identified and reported by Simon Dowling and Jean-Charles Caillère. It does not stand alone in this landscape; a ringfort lies approximately 140 metres to the north-north-east, and further ringforts and enclosures are scattered through the surrounding area, pointing to a countryside that was once considerably more structured and settled than the open tillage fields now suggest.
