It was not surveyed, not recorded, not remarked upon in any official cartographic tradition. The only reason we know it exists at all is because a plane flew over it in 1986 and a camera caught something the ground had been quietly holding for millennia.

The site is a ring-barrow, a type of low circular earthwork typically enclosing a central burial mound and defined by a surrounding ditch or bank, raised during the Bronze Age or earlier as a marker for the dead. This particular example sits in improved pasture roughly 30 metres south of a small watercourse, and it is one of three barrows aligned in a northwest to southeast orientation, suggesting the arrangement was deliberate rather than incidental. The group was identified during the Bruff aerial photographic survey of 1986, recorded under reference Bruff 103.03. That aerial discovery was the first formal acknowledgement of the monument. Its circular form has since been confirmed as a cropmark visible on Ordnance Survey orthophotography taken between 2005 and 2012, and again on a Google Earth image dated 18 November 2018. Cropmarks of this kind appear when buried features affect how vegetation grows above them, typically showing as rings of lusher or more stressed growth depending on the season and soil conditions. The field boundary about 170 metres to the south marks the townland limit with Arrybreaga.

There is nothing visible at ground level to indicate the barrow is there. No mound breaks the surface of the pasture, no earthwork announces itself to a passing walker. The monument exists, for practical purposes, as information rather than as landscape. Anyone curious enough to locate the field using the coordinates associated with the recorded monument cluster, reference LI033-112001 to 003, will be looking at ordinary improved grassland. The best way to appreciate what lies beneath is to seek out the aerial images themselves, where the circular cropmark reads clearly against the surrounding field. Late summer, when crops and grasses are under the most moisture stress, tends to produce the sharpest cropmark definition, though the site here is in pasture rather than tillage, which can make the signal more variable from year to year.
