No earthwork survives above ground, no ring of stones, no obvious depression; the only evidence of this enclosure is a cropmark, the faint ghostly signature that buried archaeology leaves on growing crops when differential soil moisture causes plants to ripen unevenly. From above, the outline of a substantial circular feature becomes readable, a trace pressed into the landscape by whatever was built or dug here long ago.

The site came to attention through aerial photography carried out by M. Moore in July 2006. Cropmarks of this kind are typically produced by features such as ditches or pits cut into subsoil, which retain moisture longer than the surrounding ground and feed the plants above them more generously. The result, visible during dry spells when crops are under stress, is a darker or more vigorous line of growth that maps the buried feature from altitude. Circular enclosures detected this way can represent a wide range of things, from prehistoric ring ditches and burial monuments to the enclosing ditches of early medieval settlements, and without excavation it is rarely possible to say which category a given site belongs to. This one has not, on current evidence, been excavated or dated.
