It cannot be seen from the road, and there is nothing visible on the ground to suggest it is there at all. What gives it away is a circular cropmark, a phenomenon where buried or levelled features beneath the soil cause grass or grain above them to grow differently, often showing as a faint ring when viewed from altitude. That ring, approximately 26 metres in diameter, is the only surviving trace of a structure that was once significant enough to warrant enclosing.

The site was first identified not by a field survey but by aerial photography. Photographs taken on 16 April 1974, catalogued under reference GSIAP R. 494, revealed the cropmark to researchers working from the air. The enclosure had already been levelled by that point, its physical form long gone, but the soil beneath continued to hold the memory of it. The mark reappeared on an Ordnance Survey orthophoto taken between 2005 and 2012, and again on a Digital Globe orthoimage from 2011 to 2013. As recently as 28 June 2018, a Google Earth orthoimage confirmed the cropmark was still legible. The record was compiled by Martin Fitzpatrick and uploaded in April 2021, placing it formally within the national catalogue of archaeological sites, though the enclosure itself remains unexcavated and undated.

Because there is nothing to see at ground level, this site is of particular interest to those curious about how archaeology is practised rather than those seeking a visible monument. Cropmarks of this kind tend to be most pronounced during dry summers, when moisture stress reveals the differential growth above buried features most clearly. The site lies in ordinary farmland, and access would require the landowner's permission. What a visitor might reasonably do instead is examine the orthoimages available through Google Earth and the National Monuments Service, where the circular form reads with quiet clarity against the surrounding pasture.
