The main feature was a large stone known as the Giants Rock, marked on early Ordnance Survey maps, which bore seven cupmarks; circular depressions carved into the stone surface. These ancient markings were arranged in two triangular patterns, with one cupmark standing alone. The site originally sat in low-lying scrubland, though extensive land reclamation has since transformed the landscape beyond recognition.

Kinahan’s survey revealed this wasn’t an isolated monument but part of a wider sacred landscape. About a hundred yards east stood another substantial flat stone called the Giants Grave, decorated with two cupmarks. The surrounding area yielded more examples of this prehistoric art form, including a rock surface with two or more cupmarks and a smaller stone roughly fifty yards south bearing a single cupmark. These cupmarked stones, likely created during the Neolithic or Bronze Age, may have served ritual purposes or acted as territorial markers for the communities who once inhabited this corner of Donegal.

Despite their historical significance, these stones have proved elusive to modern archaeologists. During recent surveys, none of Kinahan’s documented cupmarked stones could be relocated, victims perhaps of the dramatic changes that have reshaped this stretch of coastline. The archaeological record of this site now exists primarily through Kinahan’s detailed observations from the 1870s and 1880s, preserved in the Archaeological Survey of County Donegal and serving as a reminder of how much of Ireland’s prehistoric heritage has been lost to development and changing land use.
