A circular cropmark just four metres in diameter appears in satellite imagery from the summer of 2018, its outline traced not by any standing stone or earthwork but by the differential growth of crops over a buried feature below. This is a ring-ditch, the faint remnant of what was most likely a circular trench dug around a burial or monument in prehistoric times. As the soil above the filled ditch retains slightly more moisture than the surrounding ground, whatever is planted above it grows a little differently, and on a dry summer's day that difference becomes visible from altitude, though not from eye level.

The cropmark at Connahy was identified by Simon Dowling using Google Earth Pro, working from Digital Globe imagery dated 28 June 2018. Small as it is, it does not sit in isolation. A second ring-ditch of similar character lies roughly 60 metres to the north-west, and a cluster of further examples occupies the field immediately to the east. Ring-ditches of this kind are distributed widely across Ireland and are typically associated with Bronze Age funerary or ceremonial activity, though their precise function can vary considerably and is often impossible to determine without excavation. What the concentration around Connahy suggests is that this unremarkable-looking agricultural landscape preserves, just beneath its surface, traces of repeated and possibly organised use over a long period.
