The circular enclosure here exists, as far as current knowledge goes, only as a cropmark, a phenomenon where buried ditches and earthworks cause the crops or grasses above them to grow at slightly different rates, producing ghostly outlines that become legible only from the air. It was precisely this that revealed the site, when an aerial photograph taken in July 1989 showed the faint but unmistakable traces of three concentric fosses, that is, ditches, arranged in a circle roughly thirty metres in diameter.

Three concentric ditches is not a casual arrangement. A single fosse might enclose a farmstead; three suggest something more deliberate, whether a concern for defence, a gradual accretion of boundaries over time, or a site of some social or ceremonial significance within its local landscape. What can be said is that the enclosure does not sit in isolation. Another enclosure lies approximately forty metres to the south-east, and the whole area falls within a broader field system, suggesting a stretch of land that was organised, worked, and bounded across a long period of human activity. A modern field fence running north-east to south-west cuts across the eastern side of the cropmark, a small reminder that later land use has continued to reshape whatever was once here.
