This ancient monolith measures 1.17 metres in height, with a base width of 0.75 metres tapering to a thickness of just 0.22 metres. The stone has been cleverly incorporated into the dry stone wall that borders the road, a common practice in rural Ireland where prehistoric monuments often find themselves repurposed as boundary markers or building materials by later generations.

The stone occupies a particularly scenic spot on a natural ledge along the southern side of the Glencolumbkille valley, commanding views across the western end of this historically rich landscape. Its proximity to St. Faned’s Well suggests a continuity of sacred significance at this location; many Irish holy wells were established at sites already considered special in pre-Christian times, with standing stones frequently marking places of ritual importance dating back to the Bronze Age.

While the exact purpose and age of this particular stone remain unknown, standing stones in Ireland typically date from between 3000 BCE to 1000 CE and served various functions; from territorial markers and burial monuments to astronomical alignments and ceremonial gathering points. The Glencolumbkille area is particularly rich in archaeological remains, with numerous megalithic tombs, court cairns, and other standing stones scattered throughout the valley, creating a landscape where thousands of years of human history exist side by side with working farmland.
