What makes this one quietly arresting is its position: it was not placed at a summit for maximum visibility, but rather settled into the southern side of a valley, on a platform of ground that overlooks the inlet known as Sea Hole on the island's eastern edge. It is a considered placement, sheltered yet deliberate, as though whoever built it wanted it to face the water rather than announce itself to the interior.

The cairn measures some fifteen metres in length, as recorded by Gabriel Cooney in 2009, and it sits within a landscape shaped by other monuments of a similar character. To the south, the ground climbs toward Heath Hill. To the north, the skyline is given over to a separate cairn on Tinian Hill, which does occupy the kind of commanding position that this one quietly refuses. The relationship between the two monuments, one elevated and prominent, the other tucked into a valley spur, suggests something about how the island's prehistoric inhabitants understood and organised their terrain, though the precise function and date of the cairn have not been established from the available notes. The site was compiled as part of a broader survey by Geraldine Stout, uploaded in August 2011.

Lambay Island is privately owned and access is not generally open to the public, so any visit would require prior arrangement. The cairn itself lies on the eastern side of the island, and the approach through the valley would bring Tinian Hill's monument into view as a reference point to the north. The inlet of Sea Hole, which the cairn overlooks, gives some sense of why this spot might have mattered to early inhabitants; it is a specific, functional feature of the coastline rather than open sea, and the cairn's orientation toward it is one of the more intriguing things about its siting.
