It stands 1.4 metres high, its plan roughly subrectangular, measuring about 1.1 metres by 0.6 metres, with its long axis oriented northeast to southwest. That orientation is worth noting: many Irish standing stones share alignments that may relate to solar or lunar events, though whether that applies here is not recorded. What is certain is that someone, at some point in prehistory, chose this south-facing slope and decided it was the right place.

Standing stones of this kind are among the most enigmatic monuments in the Irish landscape. They appear across the country in their thousands, erected at various points during the Bronze Age and possibly earlier, and their original purposes remain largely a matter of debate. Some mark burial sites, some appear to be territorial or boundary indicators, some may have served as waymarkers, and some seem to have functioned within wider ritual landscapes. Without excavation or associated finds, the stone at Kilberrihert keeps its own counsel. Its subrectangular form, neither a rough pillar nor a carefully dressed slab, is fairly typical of the type found across County Cork.
