This ancient monolith, located in the townland of Glaisigh Daibhéid, stands 1.74 metres tall and measures roughly half a metre wide. The stone leans slightly off vertical and is oriented along a northeast to southwest axis, its weathered surface bearing silent witness to centuries of Irish weather and history.

Standing stones like this one are amongst Ireland's most enigmatic prehistoric monuments, typically dating from the Bronze Age period between 2500 and 500 BCE. While their exact purpose remains debated by archaeologists, these stones may have served as territorial markers, commemorative monuments, or held ritual significance for the communities that erected them. The considerable effort required to transport and erect such a substantial stone suggests it held real importance for the people who placed it here, overlooking the river valley below.

The stone's location on the southeastern slope of Boulty Patrick mountain places it within a landscape rich in archaeological features typical of Donegal's ancient past. The surrounding forestry now obscures much of the wider vista, but when erected, this stone would have commanded views across the Reelan valley, perhaps marking an important route, boundary, or sacred site for the Bronze Age inhabitants of this corner of northwest Ireland.
