They are invisible to anyone walking the ground, betrayed only from the air, where differences in soil moisture cause overlying crops or grass to grow at subtly different rates, leaving faint circular traces known as cropmarks. The northernmost of the three measures only about six metres in diameter, a modest ring defined by the cropmark of a fosse, which is simply a ditch cut into the earth.

Ring-ditches of this kind are typically the eroded remnants of prehistoric burial monuments, most often Bronze Age round barrows whose central mounds have been ploughed or weathered flat over millennia, leaving only the encircling ditch as evidence of what once stood above ground. What makes this particular group quietly compelling is their arrangement: three monuments positioned on a north-south alignment, with the middle example sitting just six metres south of this northernmost one, and the third roughly fifty metres further south again. That spacing and orientation suggest a deliberate relationship between the three, possibly a family cemetery or a ritual landscape laid out with some care by the people who built it. The site was identified from Google Earth aerial imagery captured in July 2018, a reminder that aerial photography continues to reveal archaeology that centuries of agriculture have effectively buried in plain sight.
