It is not dramatic in scale, just 1.55 metres tall and 0.35 metres wide, but its placement and orientation suggest that whoever erected it was paying close attention to the landscape around them. The stone is roughly triangular in section and aligned north-west to south-east, a directional choice that may reflect astronomical or territorial concerns, though the precise reasoning, like so much about Irish standing stones, has not survived.

Standing stones of this kind are among the most enigmatic monuments in the Irish countryside. Erected during prehistory, most likely in the Bronze Age, they appear across Cork in considerable numbers, sometimes singly, sometimes in pairs or alignments. Their purposes remain genuinely unclear. Some seem connected to burial sites, others to boundaries, and others still may have served as waymarkers or focal points for gatherings. The Lahernathee example, with its deliberate narrowing profile and careful orientation on a ridge, fits recognisably within this tradition without giving much else away.
