This one, in the townland of Towlerton in County Limerick, survived for millennia in quiet obscurity, and continues to do so. It came to light in 2004, when archaeological monitoring during construction of the Castletroy distributor road caught it before the machinery could move on. It is a modest stone by any measure, standing 1.1 metres high, 0.65 metres wide, and just 0.2 metres thick, oriented with its long axis running north to south. No packing stones were visible at its base when it was recorded, which is unusual; standing stones are typically steadied with smaller stones wedged around their base during erection, and the absence of any visible trace here leaves open questions about how it was set and how it has remained upright.

The stone sits on level ground at the foot of a northeast-facing slope, roughly 110 metres from the floodplain of the Groody River. That kind of positioning, close to water and on transitional ground between slope and plain, is consistent with how prehistoric communities in Ireland often placed such monuments, though what specific purpose this one served remains unknown. What adds a further layer of interest is its proximity to a fulacht fiadh located around 160 metres to the southeast. A fulacht fiadh is a type of ancient cooking or processing site, typically identified by a horseshoe-shaped mound of fire-cracked stone beside a trough, and they are among the most common prehistoric monument types in Ireland. Whether the standing stone and the fulacht fiadh were related in function or simply reflect repeated use of the same productive landscape over time is not something the current record can answer.

The stone is not clearly visible from the ground, which makes locating it something of a small puzzle. A thorn tree growing nearby serves as the most reliable marker, identifiable on satellite imagery taken in November 2019, and that is likely the most practical guide for anyone trying to find it. The surrounding area has been substantially altered by road construction and suburban development, so the approach is more industrial than pastoral. Visitors with a serious interest in prehistoric landscape archaeology, or those curious about what road schemes occasionally turn up in the process of building the mundane infrastructure of modern life, will find something thought-provoking in its continued, quietly stubborn presence beside the Groody floodplain.
