It is not a dramatic monument. At just over one and a half metres tall and roughly subrectangular in plan, with its long axis running north to south, it is the kind of thing you might walk past if you did not know to look. What makes it quietly curious is that it appears to have gone entirely unrecorded by the Ordnance Survey cartographers who mapped this part of County Cork in 1842, suggesting it was either obscured, overlooked, or simply not considered worth marking at the time.

Standing stones of this type are among the more enigmatic features of the Irish landscape. They were erected across a broad span of prehistory, most commonly during the Bronze Age, and their purposes remain genuinely uncertain. Some are thought to mark boundaries, routeways, or burials; others may have carried astronomical or ceremonial significance. Without excavation, the stone at Gortnapeasty offers no firm answers. Its dimensions, roughly 0.84 metres by 0.5 metres at the base, suggest a modest but deliberate installation, shaped or selected for its roughly rectangular form and set with some intention into this sloping ground in mid-Cork.
