The feature is a cairn, a term used broadly for a deliberate grouping or heap of stones, and this one is unusually modest even by the understated standards of Irish prehistoric monuments. It measures roughly 1.6 metres east to west and just under 1.5 metres north to south, with a shallow depression of about 15 centimetres at its deepest point. Five or six sizeable boulders are arranged around a central stone that sits at the base of that depression, all of them embedded in the turf with only their upper surfaces breaking through the sod. The grass grows so thickly over them that the stones only reveal themselves when the vegetation is pressed down and pulled aside.

What makes the site quietly curious is its placement and its company. The cairn sits in the south-western corner of a rectangular enclosure, a type of bounded space that in Irish archaeology can indicate anything from a domestic settlement to a ritual or funerary complex. Some 36 metres to the east-south-east lies a possible mound barrow, which is a raised earthen burial monument of the kind built across Ireland and Britain during the Bronze Age, and roughly 30 metres to the north-east stands a further enclosure. Whether these features were conceived together or accumulated across different periods is unknown, but their proximity gives the field a layered quality that its unremarkable surface does nothing to advertise. The cairn itself has no confirmed date or excavation history in the available record, and its function remains uncertain.
