That position is not coincidental. Cairns, which are prehistoric burial or memorial monuments typically consisting of a heaped mass of stones, were frequently placed at territorial junctions in the landscape, serving as fixed markers that generations of people agreed to respect and navigate around. This one is roughly circular, approximately eighteen metres across and three metres high, and while it reads at a glance as a grassy hummock, the underlying stonework is still evident to anyone who looks carefully at its profile.

The cairn appears in Liam Price's 1940 survey of the area, one of the earlier scholarly attempts to document such monuments in County Dublin, which at least establishes it was recognised as a site of significance before the more serious damage began. The stones that once formed the upper portion have been robbed, probably for field walls or other local construction over the centuries, and no kerbstones, the upright stones that would originally have defined the monument's outer edge, are now visible. The southwestern quadrant has been absorbed into plantation forestry, and a drainage channel running northeast to southwest cuts directly into the body of the monument. In 1994, a newly constructed forest road was driven through the northern base of the cairn, compounding losses that had already accumulated over a long period. At some point, a shooting hide was built on top of the mound, an arrangement that is unfortunately not unusual on upland monuments that sit within managed shooting estates.

The hill is accessible on foot from the Ballinascorney area, though the terrain is open upland and can be boggy underfoot, so boots and weatherproof clothing are sensible regardless of the season. The forestry around the southwestern side means the monument is not fully visible from any single approach, and the combination of tree cover, drainage works, and road cutting makes the overall extent of the original cairn difficult to read on the ground. Coming from the northeast gives the clearest view of what remains of the mound's profile. The boundary junction that originally defined its placement is still the meeting point of three townlands, which means the cairn, whatever its current condition, continues to occupy the exact geographical role it was given thousands of years ago.
