This modest monument, carved from rough stone, rises just 70 centimetres from the ground and would have originally stretched about 35 centimetres across its arms, though time has taken its toll; the southern arm has long since broken away. The cross occupies a flat terrace of rough pasture that drops sharply towards the waters of the bay to the east, offering visitors expansive views across the landscape.

The cross represents one of countless early Christian monuments scattered throughout Donegal, each marking a place of significance to local communities across the centuries. Its simple, roughly cut form suggests it may date from the medieval period, when such crosses served multiple purposes; as waymarkers for pilgrims, memorials for the deceased, or focal points for outdoor religious gatherings. The modern shrine that now shelters it speaks to the continuing reverence local people hold for these ancient markers, ensuring their preservation even as the original context and meaning may have been lost to time.

This particular cross was documented as part of the Archaeological Survey of County Donegal, a comprehensive catalogue compiled in 1983 that recorded field antiquities from the Mesolithic period through to the 17th century. Its weathered surface and broken arm serve as tangible reminders of the passage of centuries, whilst its position above Mulroy Bay connects it to the broader sacred landscape of medieval Donegal, where Christianity and older traditions intertwined to create a unique spiritual geography.
