The flowers follow the curve of an ancient fosse, the shallow ditch that once defined a ditch barrow, a type of prehistoric burial monument in which a circular trench rather than a raised mound is the primary surviving feature. The interior of the circle sits just five centimetres below the level of the surrounding ground, a difference so slight it would be invisible to anyone not looking for it, yet enough to have preserved the monument's basic geometry across millennia.

The site is modest in scale, roughly six metres north to south and just over five metres east to west, with the fosse itself around two metres wide and now only fifteen centimetres deep. It was first formally identified not on the ground but from the air, appearing as a ring-ditch on an aerial photograph. Ring-ditches are the cropmark signatures of prehistoric monuments, visible when differential soil moisture causes the filled-in ditch to show up as a darker or lighter band of vegetation from above. What makes this particular site quietly interesting is that it does not sit in isolation. Two further ring-barrows lie to the north-north-west, and all three appear to be conjoined, suggesting this was once a small cluster of related funerary monuments rather than a solitary grave. Such groupings are not uncommon in the Irish landscape, where the dead were sometimes buried in deliberate proximity to one another, the monuments touching or overlapping as if in conversation.
