In a field in Broadfield, County Kildare, the ground itself is doing the talking. A circular enclosure roughly 27 metres in diameter has left no upstanding walls, no earthworks visible to a passing eye, and no obvious marker on the landscape. What it has left is a cropmark, the kind of faint but telling trace that only reveals itself from the air, where differences in soil depth and moisture cause crops to grow at subtly different rates above buried features, outlining the ghost of a structure that has otherwise vanished.

The enclosure came to wider attention through Google Earth aerial imagery, with a photograph taken on 28 June 2018 showing the circular outline clearly enough to document. What the image also revealed is that the site has not been left entirely undisturbed: the southwestern portion appears to have been partially quarried into at some point, removing a section of whatever buried archaeology remains. Circular enclosures of this kind are found across Ireland and can date from the Bronze Age through to the early medieval period, associated variously with settlement, ritual, or burial. Without excavation, the precise date and function of the Broadfield example remain open questions.
