No earthwork rises from the ground, no visible bank traces the outline of what was once there. The only way to observe it is from above, and specifically from a satellite image captured on a particular July day in 2018, when the geometry of a buried past briefly announced itself through differential crop growth.

What the image reveals is a cropmark, the faint signature left in growing vegetation when buried features alter how deeply roots can reach or how much moisture the soil retains above them. Here, the mark describes a subcircular enclosure roughly 47 metres across on its east-northeast to west-southwest axis and about 42 metres on the north-northwest to south-southeast, defined by a slight fosse, meaning a shallow ditch that once formed the boundary of the enclosed space. There may be an entrance roughly two metres wide on the northern side. Cropmarks of this kind are often associated with early medieval ringforts or earlier prehistoric enclosures, though without excavation the date and function of this one remain open questions. The site was first reported by Simon Dowling, and its existence has since been complicated slightly by later agricultural activity: a field bank runs east-northeast to west-southwest just south of the centre, cutting across what lies beneath, while a second bank grazes the eastern perimeter from the north-northwest to south-southeast. The enclosure, in other words, has been partly overwritten by the practical geometry of farming, its circular logic interrupted by the straight lines of later land division.
