This ancient standing stone, measuring 1.25 metres in height and 1.4 metres in width, is almost perfectly square in plan and oriented along a north-northeast to south-southwest axis. Though it escaped the attention of early Ordnance Survey mapmakers in 1836, by 1907 it had earned its place on official maps, marked simply as 'Standing stone'.

The significance of this modest monument became clearer in the 1960s when archaeological discoveries revealed it wasn't standing alone in prehistory. In 1964, excavations uncovered a Bronze Age burial in close proximity to the stone, followed two years later by the discovery of a cist burial approximately 180 metres to the south, likely also dating to the Bronze Age. These finds suggest the area around Laheen Hill held special meaning for ancient communities, serving as a sacred landscape for both ritual and burial practices.

Today, the standing stone remains accessible from the roadside verge, offering visitors a tangible connection to Ireland's Bronze Age past. Above it on Laheen Hill sits a rath, or ringfort, adding another layer to the area's archaeological richness. Together, these monuments create a palimpsest of ancient Irish life; from Bronze Age burial grounds to later defensive settlements, all set within the gentle, undulating countryside of Donegal.
