Most standing stones are rough-hewn slabs, broad and blunt against the sky. This one is a triangular limestone pillar, its cross-section more like a blade than a block, and across its faces run white streaks of quartzite that catch the light in a way that plain grey stone does not. It is a quietly singular object in a county that tends not to advertise its prehistoric monuments.

The stone was recorded in detail between 1942 and 1943 by O'Kelly, who noted that it stands 2.4 metres tall, with a base width of around 86 centimetres and a thickness of only 15 centimetres. Those proportions, tall and narrow and sharply angled, give it an almost architectural quality. It sits in a field to the north-east of Barnanenagh Fort, a ringfort of the kind common across Ireland, typically a circular earthen or stone enclosure used as a defended farmstead during the early medieval period. Whether the standing stone predates that fort by millennia, as many such stones do, or whether the two features were ever understood in relation to one another by the people who lived here, is not recorded. What is clear is that they share the same field, and that the association between upright stones and enclosures of various periods is not unusual in the Irish landscape.

The site sits in Co. Limerick, near Castlefarm. Access to sites of this kind in agricultural land typically requires awareness that the ground may be private farmland, so approaching with consideration is advisable. The stone's limestone composition and its quartzite veining are worth examining up close if you can reach it; the white streaks are not decoration but a natural feature of the rock, and on a bright day they are genuinely striking. The neighbouring Barnanenagh Fort is recorded separately and provides useful orientation when trying to locate the stone within the field.
