Ring-ditches of this kind are invisible at ground level for most of the year, yet under the right conditions, typically a dry summer when shallow soils over ancient ditches retain slightly more moisture, the grass or grain above them grows fractionally taller and greener, tracing out circles that can only be read properly from the air.

The pair at Bawnoge came to notice through a Google Earth photograph taken in July 2018, a period of dry weather when cropmarks across Ireland and Britain became unusually legible. The two ring-ditches sit roughly four metres to the south-south-east of a larger enclosure, also identified as a separate monument in the record. Ring-ditches of this type are generally understood to be the ploughed-down remains of Bronze Age round barrows, the circular burial mounds that once defined the funerary landscape of prehistoric Ireland. Over millennia of cultivation, the mound itself disappears entirely, but the encircling ditch, cut into the subsoil, persists as a buried feature long after the surface has been levelled. The proximity of the two ring-ditches to the larger enclosure nearby suggests this corner of Bawnoge was a place of some significance in the prehistoric landscape, though the precise relationship between the monuments remains a matter for further investigation.
