It measures just 1.25 metres in height, roughly rectangular in plan, tapering slightly towards the top, and oriented along an east-west axis. What makes it quietly arresting is not its scale but its context: it sits within a network of relict field boundaries, the ghostly outlines of agricultural systems long since abandoned and swallowed by the encroaching bog. The stone protrudes through the surface of that bog, which both preserves and obscures the landscape around it.

Standing stones are among the most enigmatic monuments in the Irish archaeological record. Erected most commonly during the Bronze Age, though sometimes earlier or later, they resist easy interpretation. Some appear to mark boundaries, burials, or routeways; others may have had ceremonial or astronomical significance. The east-west orientation of this particular stone is notable, aligning broadly with the rising and setting of the sun at the equinoxes, though whether that alignment was intentional remains unknown. What adds further interest is the presence of a second standing stone approximately 120 metres to the north-west. Two stones in relative proximity suggest that this corner of Knocknagullion was not a place of isolated, incidental monument-building, but part of a more deliberate arrangement within a landscape that was once actively farmed and organised.
