It leans slightly to the north-north-east, its rectangular shape orientated roughly east-north-east to west-south-west, and cattle have worn a shallow depression around its base over the years. What makes it quietly interesting is not the stone alone but what appears to be clustered around it at ground level, much of it half-buried beneath grass tufts.

Standing stones are among the most common prehistoric monuments in Ireland, raised during the Bronze Age or earlier, and their original purposes remain broadly debated: boundary markers, ritual foci, burial indicators, or some combination of these. At Ballyknock, the question of purpose becomes a little sharper on closer inspection. O'Brien, writing in 2006, noted a group of smaller stones protruding from the ground immediately to the north of the main upright. These could be packing stones, the kind used to stabilise a standing stone in its socket, but O'Brien raised another possibility: that they form a cist, a small stone-lined grave box of the kind often associated with Bronze Age burials, measuring roughly 0.4 by 0.5 metres, made up of two short side stones and one longer stone, with the base of the standing stone itself serving as the back wall. If that reading is correct, the upright and the cist were conceived together, the monument functioning as both marker and burial structure. The large packing stone visible at the base, along with others that may still be hidden by vegetation, suggests the original installation was carefully done.

The site sits in improved pasture with open views from east to north-west, so the stone is visible across a reasonable distance on the hillside. The depression worn by grazing cattle around the base is worth noting as a reminder of how unprotected many of these monuments remain in agricultural land.
