The standing stone at Glasnamullen in County Wicklow is a quiet thing, rising just 0.8 metres from the ground, roughly the height of a garden wall. What makes it quietly worth attention is the care of its placement: a block of local granite, oriented along a north-south axis and set deliberately onto a small raised platform on a gentle south-east-facing slope. Someone, at some point in prehistory, chose this spot and this orientation with apparent intention, even if their reasoning is now entirely lost to us.

Standing stones are among the most enigmatic survivals in the Irish landscape. They date, in most cases, to the Bronze Age, though precise dating of individual examples is rarely possible without associated finds or excavation. Their purposes are debated, ranging from boundary markers and memorial stones to ritual or astronomical alignments. This particular stone, a slab of granite measuring 0.65 metres by 0.3 metres, is modest in scale but consistent in character with many others scattered across Wicklow's uplands. The detail of its small platform is notable; that slight raising of the stone above its immediate ground level suggests deliberate construction rather than casual placement. The information on record comes from P. Neary, and the stone is catalogued in the Archaeological Inventory of County Wicklow, published in 1997.
