Roughly D-shaped in plan, measuring approximately 18 metres east to west and 12 metres north to south, and rising to about 1.3 metres in height, it sits quietly in ordinary farmland with a modern field fence running along its straight southern edge. That fence, rather than any ancient boundary, defines the flat side of the D, which is itself a small clue that something here may not be quite what it seems.

The feature does not appear on any edition of the Ordnance Survey six-inch maps, the standard historical record against which Irish field monuments are routinely checked. Its existence as a potential antiquity came to light only through aerial photography, and on that basis it was included in the Record of Monuments and Places in 1995 as a possible enclosure. An enclosure in this context typically refers to a defined area bounded by a bank, ditch, or wall, often associated with early settlement, agriculture, or ritual use. The qualifier here matters, however. Those who examined it have noted plainly that it may be a naturally-occurring feature rather than a genuine antiquity, meaning the slight rise in the ground could simply be a product of geology or soil deposition rather than human intention. It is, in other words, a monument to uncertainty as much as anything else.
