This is a ringfort, the most common archaeological monument type in Ireland, built during the early medieval period as a defended farmstead, typically a circular area enclosed by one or more earthen banks and ditches. What makes this particular example quietly interesting is not grandeur but survival, and the way its history has been quietly complicated by an adjacent quarry that no longer exists.

The ringfort measures roughly 53 metres across in both directions, making it a reasonably substantial example of the type. It appears on the first edition Ordnance Survey six-inch map of 1840 and again on the revised edition produced between 1901 and 1905, both times shown lying immediately south of a quarry. That quarry has since been filled in, but its former presence seems to have left a mark on the interior: in the north-east quadrant, the internal ground level is raised by about a metre, possibly the result of spoil from the quarry being spread across that section. Thistles and nettles have colonised the area, the nettles in particular tracing the line of the external fosse, the shallow ditch that once ran around the outside of the enclosing bank. The east side of the monument retains a scarp nearly one and a half metres high, while the western arc has weathered considerably lower, to around a third of a metre, its bank now forming the base of a hedgerow running north to south along the field boundary. A second hedgerow follows the northern edge. The landscape, in other words, has grown around and into the monument over the intervening centuries, making the two difficult to separate at a glance.
