Visible from the air, a D-shaped outline roughly 60 metres along its longer axis and 40 metres across marks where a single fosse, a defensive or boundary ditch, was dug into the ground long ago. The soil above the filled ditch retains enough moisture or nutrients to make the grass or grain above it grow fractionally differently from the surrounding field, and that difference, invisible at ground level, resolves into a clear shape when seen from above.

The enclosure sits on a gentle south-west-facing slope, and its outline has been cut into by later field banks on two sides, one running north-west to south-east across the north-east corner, another cutting across the south-west. These banks are themselves old enough to be part of the established agricultural landscape, yet they post-date whatever settlement or activity the enclosure once contained. Inside the perimeter, near its western edge, there is a separate feature: a small ring-ditch roughly ten metres in diameter. Ring-ditches of this size are often the eroded remains of Bronze Age burial mounds, the circular trench that once surrounded a low earthen cairn, though without excavation the date and purpose of this one remains open. The combination of a D-shaped enclosure and an internal ring-ditch is a small puzzle that the aerial photographs capture but cannot fully answer.
