That quiet absence from the official cartographic record is itself a small curiosity: a prehistoric standing stone that has simply gone unregistered in the landscape most people navigate by, yet remains entirely present in the actual one. It rises 1.68 metres from the ground, tapering from a broad base to a rounded top, its ground plan an angular, pear-shaped form of five facets, the two longest sides measuring 1.2 metres and 1.1 metres respectively, oriented roughly northwest to southeast.

Standing stones are among the most enigmatic of Irish prehistoric monuments. Erected most commonly during the Bronze Age, though sometimes earlier, they resist easy interpretation: proposed functions range from territorial markers and ritual focal points to astronomical alignments and burial indicators. Many were set on elevated or open ground, and this one at Kilgobnet follows that pattern, positioned on land that opens out to broad views eastward. The choice of limestone, with its distinctive pale colouring and tendency to weather into irregular facets, gives the stone a presence that is less about imposing height than about the subtle geometry of its five-sided form, which tapers unevenly, as though the shaping was deliberate but unhurried.
