It stands 2.7 metres tall, measures 1.8 metres across its base, and tapers to roughly 0.8 metres in thickness, giving it an irregular, almost wedge-like profile when viewed from different angles. It is orientated north to south, a detail that may or may not be deliberate, since many standing stones across Ireland share broadly similar alignments, though the reasons behind any individual example are rarely certain.

Standing stones, sometimes called galláin in Irish, are among the most enigmatic monuments in the Irish landscape. They date most commonly to the Bronze Age, though some may be earlier or later, and their original purposes remain contested. Some appear to mark boundaries, routeways, or burials; others may have had ceremonial or astronomical functions. This particular stone in Deerpark sits in open pasture, which is typical enough, but the presence of what appear to be packing-stones in the ground nearby is a small and telling detail. These are the stones used to wedge and stabilise a standing stone when it was first erected, and their survival close to the surface suggests the monument has remained largely undisturbed where it was originally set.
