Archaeological surveyor Van Hoek documented at least one definite cup mark carved into a ridge that runs parallel to, and slightly north of, the main ridge known as DON 11. These simple circular depressions, pecked into the rock face thousands of years ago, represent one of humanity’s earliest forms of artistic expression in Ireland.

The site itself presents something of a mystery, as much of the ridge remains covered in vegetation, making a comprehensive survey difficult. Van Hoek suspected that more engravings likely exist beneath the overgrowth, waiting to be discovered. Cup marks like these are found across Ireland and Britain, typically dating from the Neolithic to the Bronze Age period, roughly 4000 to 1500 BCE. Their purpose remains debated amongst archaeologists; some suggest they held ritual significance, whilst others propose they may have marked territories, tracked astronomical events, or simply served as artistic expression.

What makes this particular site intriguing is its relationship to the nearby main ridge, catalogued as DG004-063. The parallel positioning of these ridges, both potentially bearing rock art, hints at a deliberate choice by our ancestors. Perhaps this landscape held special meaning for the communities who once lived here, transforming natural rock outcrops into canvases for their mysterious symbols. Until the vegetation is cleared and a full survey conducted, we can only speculate about what other prehistoric artwork might be hiding in plain sight on these Donegal hillsides.
