This ancient monolith measures 1.35 metres in height and just over a metre in width, with a substantial thickness of 55 centimetres. Oriented along an east-west axis, the stone occupies a gentle slope that descends southeastward towards the waters of Lough Foyle, offering commanding views across the surrounding farmland.

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. Whilst their exact purpose remains a subject of archaeological debate, these stones may have served various functions; as territorial markers, commemorative monuments, or perhaps as part of ancient astronomical observations. The careful positioning of the Cabry stone, with its specific orientation and prominent location overlooking the lough, suggests it held particular significance for the communities who erected it.

The stone's survival through millennia speaks to both its robust construction and the respect it has commanded from successive generations of local inhabitants. Today, it stands as a tangible link to Donegal's deep prehistoric past, a silent witness to the countless changes that have swept across this corner of Ireland whilst it remained firmly rooted in place. Its presence reminds us that this seemingly quiet rural landscape has been home to human communities for thousands of years, each leaving their own subtle marks upon the land.
