The monument itself is modest in appearance: two upright pillar stones, the taller standing around 1.4 metres high, set roughly 7.8 metres apart at either end of a low, elongated mound of earth and large stones. The mound runs just over ten metres from north-northwest to south-southeast and rises only between 0.3 and 0.7 metres from the ground. It sits on a gentle north-facing slope, with a separate cairn, a heap of stones that may itself mark a prehistoric burial, lying some 130 metres to the south-southeast.

When the antiquarian Liam Price examined the site in 1934, he recorded the two pillar stones carefully, noting their heights and widths, and observed that the taller of the pair stood to the east-southeast of the other. His account is precise on the physical detail but candid about the limits of local knowledge: "I know of no tradition concerning this monument," he wrote. That absence is itself telling. Whatever ritual, funerary, or territorial purpose the structure once served, no story attached to it survived into living memory by the early twentieth century. The "Giant's Grave" name on the map is the only residue of popular interpretation, a placeholder for something people recognised as ancient but could no longer explain.
