It leaves no mark on the surface, no rise in the ground, no scatter of stone. The only way it has ever been seen is from the air, when the right crop grows over it in the right dry summer and betrays, through uneven growth, the buried boundaries beneath.

What aerial photography captured on 19 July 1971, as part of the Cambridge University Collection of Aerial Photography (reference BGN094), was a large, irregularly shaped enclosure measuring roughly 120 metres on its northeast to southwest axis and around 60 metres across. Cropmarks, which appear when buried ditches or walls affect how plants above them grow, revealed not only the outer enclosure but also a smaller D-shaped enclosure sitting within it. The outer boundary appears to continue northeast of the public road for a further 100 metres or so, suggesting the whole complex may form part of a wider field system rather than a single discrete structure. The relationship between the two enclosures points to a layered, organised use of this land at some point in the past, though the notes do not tie the site to a particular period or culture. What remains is the outline of something purposeful, preserved only in a single photograph taken on a July afternoon more than fifty years ago.
