What makes it quietly remarkable is the cross carved into its north-west face: a single-line grooved Latin cross whose arms extend all the way to the edges of the stone, with a subcircular depression at its head. The pillar itself tapers from roughly fourteen centimetres at the base to nine at the top, narrowing gradually to a point, giving it a shape somewhere between a standing stone and a rough-hewn obelisk.

Pillars like this belong to a tradition of early Christian stone carving found across Ireland, where pre-existing standing stones were sometimes appropriated and marked with a cross as a way of Christianising the landscape. The association here with St Soorney's Well deepens that impression. Holy wells in Ireland were frequently focal points for devotion that predated Christianity and were later absorbed into it, with saints' names attached and patterns, meaning prescribed rounds of prayer, observed on particular feast days. The carved pillar nearby would have reinforced the sacred character of the site, functioning as a visible marker of Christian claim on a place that may have held significance long before. The carving style, described by researcher Higgins in 1987, is consistent with early medieval practice, though precise dating of uninscribed cross pillars is rarely straightforward.
