This particular site, documented by researcher Van Hoek, sits just a few metres southwest of another carved ridge known as DON 23. The eastern group of engravings is modest but intriguing, consisting of only two carved features: a large disc-cup and a smaller cup-mark that’s surrounded by an incomplete oval ring. These markings were carved into rock that slopes gently at seven degrees towards the east, positioned close to the natural scarp edge.

The discovery and documentation of these engravings came at a critical time. By 1988, quarrying operations had already begun transforming this ancient landscape; dynamite blasts had damaged portions of the rock outcrop where these prehistoric markings had survived for millennia. Van Hoek’s survey work in the area proved essential in recording these vulnerable archaeological features before further destruction could occur.

These cup-and-ring marks, whilst simple in appearance, represent a widespread tradition of rock art found across Ireland, Britain, and Atlantic Europe. Dating typically to the Neolithic and Bronze Age periods, such carvings remain enigmatic; their original purpose and meaning lost to time. Whether they served as territorial markers, held ritual significance, or mapped celestial observations continues to fuel archaeological debate. What remains clear is that these weathered symbols connect modern Donegal to its ancient inhabitants, who chose this particular outcrop to leave their permanent mark on the landscape.
