Seven ring-ditches occupy a single field near Jenkinstown, spaced between roughly 20 and 120 metres apart, yet none of them breaks the surface of the grass. To walk across this land is to walk across something without knowing it is there.

Ring-ditches are the crop-mark traces of prehistoric circular enclosures, most often the ploughed-down remains of burial mounds or ceremonial boundaries. Where the original earthwork has been levelled over centuries of agriculture, the filled-in ditch beneath can still hold moisture differently from the surrounding soil, causing the grass or crops above to grow in subtly distinct patterns that only become legible from the air. That is precisely how this group was found. An aerial photograph taken on 16 July 1971, catalogued as CUCAP BGG067, revealed the whole cluster at once, seven monuments that had gone unrecorded until a camera looked down from altitude. The field sits on a gently sloping terrace positioned between two rivers, the Nore flowing roughly northwest to southeast about two kilometres to the east, and the Dinin running northeast to southwest a similar distance to the west, with both rivers converging approximately two kilometres to the south. That kind of well-watered, elevated-but-not-exposed position is exactly where prehistoric communities tended to settle and bury their dead, with open views in most directions and fertile low ground close at hand.
