The monolith measures approximately 1.2 metres in height, with a width of 42 centimetres and a maximum thickness of 30 centimetres, oriented along an east-west axis. Its position offers commanding views across the Cabry Glen, which sweeps southeastward towards the waters of Lough Foyle.

This standing stone represents one of many prehistoric monuments scattered across the Donegal landscape, though its exact purpose remains enigmatic. Such stones were erected during the Bronze Age, roughly between 2500 and 500 BCE, and may have served various functions; as territorial markers, commemorative monuments, or perhaps as part of ritual or astronomical observations. The deliberate placement on elevated ground overlooking productive farmland suggests the site held particular significance for the communities who erected it.

The stone's modest dimensions and relatively isolated setting distinguish it from the more elaborate stone circles and alignments found elsewhere in Ireland, yet it forms part of the same tradition of monumental stone architecture that characterises much of the island's prehistoric landscape. Today, it continues to mark this quiet corner of Donegal, a tangible link to the area's deep past and the people who first shaped this landscape thousands of years ago.
