It shows itself only from above, and only under the right conditions: a cropmark, the kind of faint circular discolouration that appears in grass or grain when buried archaeology beneath the soil causes vegetation to grow differently from its surroundings. The enclosure was not discovered by excavation or by any boots on the ground, but by aerial photography, a reminder that a great deal of what lies beneath Ireland's farmland has never been formally recorded and may only reveal itself by accident.

The site was identified from aerial photography, specifically OS flight 740, photograph 0685, and was later confirmed on a Google Earth orthoimage captured on 19 November 2019. It was compiled into the record by researchers Alison McQueen and Vera Rahilly and uploaded to the Sites and Monuments Record in June 2020. An enclosure, in the archaeological sense, is simply a defined area enclosed by a bank, ditch, wall, or some combination of these, and in an Irish context they are frequently associated with early medieval settlement, though without excavation it is impossible to say what this particular example once contained or when it was built. A second enclosure, already recorded, sits approximately 155 metres to the south-west, which raises the possibility that what survives here is part of a wider pattern of past activity across this low-lying ground. The land overlooks the River Shannon, which runs roughly two kilometres to the north-east, a waterway that has shaped movement and settlement along this stretch of the country for millennia.

Because the monument exists only as a cropmark, there is nothing to see at ground level; the circular form is simply not visible to a visitor standing in the field. The site sits in pasture, and as with most such recorded monuments on agricultural land, there is no public access or formal infrastructure. The most useful way to observe it is through satellite imagery, where the circular outline can be picked out in the November 2019 Google Earth image when the ground conditions are favourable. For anyone with an interest in how archaeological sites are identified and catalogued, it serves as a useful illustration of how much of the Irish landscape remains unexcavated and known only as a shape in the soil.
