The stone at Killeenemer stands 1.7 metres tall, irregular in both plan and shape, with its long axis running north-east to south-west. Most striking is a large vertical fissure splitting its north-north-west face, a natural fracture that gives it an almost deliberate, architectural quality.

What makes its presence here quietly puzzling is that it went unrecorded on the Ordnance Survey six-inch maps of both 1842 and 1906, suggesting it was either overlooked by surveyors or obscured by the very fence that now incorporates it. It sits on a north-facing slope, roughly forty metres south of a bullaun stone, a type of ancient rock featuring one or more cup-shaped hollows ground into its surface, often associated with early Christian or pre-Christian ritual use. The proximity of the two monuments hints at a landscape that was once more deliberately organised than the present scatter of fields and fences suggests. Standing stones of this kind are generally prehistoric in origin, though their precise purpose, whether as boundary markers, ceremonial focal points, or astronomical indicators, remains largely a matter of interpretation.
