It stands 1.6 metres tall, rectangular in plan, measuring roughly 1.7 metres by 0.8 metres, and its long axis runs northwest to southeast. That orientation is unlikely to be accidental. Standing stones, prehistoric monoliths erected singly rather than as part of a circle or alignment, are found in considerable numbers across County Cork, and while their precise purposes remain debated, deliberate orientation towards astronomical or landscape features is a pattern observed at many such sites across Ireland.

The stone sits on a north-facing slope, which makes it the more conspicuous in the surrounding agricultural ground. Tillage fields, turned and worked season after season, are not always kind to ancient monuments, yet this one has remained upright. How long it has stood there is not recorded, but standing stones of this type are generally associated with the Bronze Age, a broad period spanning roughly 2500 to 500 BC, during which such markers were raised across the Irish landscape for purposes that may have included ritual, territorial demarcation, or the commemoration of the dead. The Mid Cork area, in which Dunisky sits, is well documented as containing a significant concentration of prehistoric monuments, and this stone fits quietly into that longer pattern of human presence on the land.
