It was not discovered by an archaeologist walking the fields or by a local farmer turning the soil. Instead, it came to light during infrastructure work, specifically the survey conducted in connection with the Bórd Gáis Éireann Curraleigh West to Limerick gas pipeline. A review of aerial photographs taken in support of that project revealed the outline of something much older lying quietly beneath the grass.

What emerged from that examination was an oval-shaped cropmark roughly 26 metres in diameter. Cropmarks occur when buried features, whether ditches, walls, or foundations, affect the growth of surface vegetation in ways that become legible from above. Filled ditches tend to retain more moisture, producing lusher, greener crops; stone foundations do the opposite. In this case, the aerial evidence was clear enough to record the enclosure as a monument in its own right, catalogued under reference LI031-062001-. It sits within a wider field system and is positioned immediately north of a second enclosure and approximately 177 metres south of a third, suggesting it was never an isolated feature but part of a broader pattern of activity in this landscape. A possible annexe to the north, recorded separately, adds further complexity. The record was compiled by Fiona Rooney and uploaded in March 2021.

Because the enclosure exists only as a cropmark, there is nothing to see at ground level in the conventional sense. The best views come from the aerial images available through Google Earth, where the oval outline can still be made out on orthophotographs taken between roughly 2005 and 2012. Visiting the area in person would mean looking at ordinary pasture, though knowing what lies beneath it changes the quality of that looking. Cropmarks tend to be most pronounced during dry summers, when differential moisture in the soil is most visible from the air, so this is a site that rewards the kind of attention usually paid to a screen rather than to a landscape.
