Measuring approximately 1.5 metres in height, 1.3 metres across, and 30 centimetres thick, this prehistoric monument stands aligned along a north-south axis. The stone occupies a strategic position on fairly fertile land, commanding views over the lower ground that stretches away to the south.

Standing stones like this one are amongst Ireland's most enigmatic archaeological features, erected during the Bronze Age between 2500 and 500 BCE, though some may date even earlier. Their original purpose remains a subject of scholarly debate; they may have served as territorial markers, commemorative monuments, or held ritual significance for the communities that raised them. The careful positioning of this particular stone, with its deliberate orientation and commanding outlook, suggests it held considerable importance for those who placed it here thousands of years ago.

The Glen Lower standing stone forms part of Donegal's rich archaeological landscape, documented comprehensively in the Archaeological Survey of County Donegal in 1983. This survey catalogued the county's field antiquities from the Mesolithic period through to the 17th century, preserving crucial information about monuments that might otherwise be overlooked or forgotten. Today, the stone continues to stand in its original position, a tangible link to Ireland's distant past and a reminder of the ancient peoples who once shaped this landscape.
