This ancient site features a large outcrop decorated with at least twelve shallow cup marks, those enigmatic circular depressions that our ancestors carved into stone thousands of years ago. The cups are scattered across various surfaces of the rock, each one a deliberate creation that speaks to the artistic and possibly spiritual practices of Ireland's early inhabitants.

The site was documented by researcher Van Hoek in 1988, who noted its position about 50 metres southeast of another archaeological feature known as DON 3. To find it, you'd cross a slight valley and look just north of an old stone wall; a typical setting for these mysterious markings that dot the Irish countryside. Cup marks like these are amongst the most common forms of rock art found across Ireland and Britain, yet their exact purpose remains one of archaeology's enduring puzzles.

What makes this particular outcrop intriguing is the sheer number of cups carved into its surface. While some sites might feature just a handful of these markings, the dozen or more at Carrowreagh suggest this location held particular significance for the people who created them. Whether they served as territorial markers, held astronomical meaning, or played a role in ritual practices, these simple yet evocative carvings continue to fascinate visitors and researchers alike, offering a tangible connection to Donegal's deep prehistoric past.
