This particular example consists of two cupmarks carved into a large boulder, located roughly 10 metres west of another documented archaeological feature known as DON 3. These simple yet intriguing markings were documented by researcher Van Hoek in 1988, who noted their position in relation to other prehistoric sites in the area.

Cupmarks, small circular depressions carved into stone surfaces, are amongst the most common forms of prehistoric rock art found across Ireland and Britain. Whilst their exact purpose remains a mystery, these markings date back thousands of years and are often found in clusters or alongside other carved symbols. The examples at Carrowreagh form part of a broader distribution of rock art across Donegal, a county particularly rich in these enigmatic stone carvings.

The preservation and documentation of sites like this one help archaeologists piece together patterns of prehistoric activity and ritual practice. Though seemingly modest; just two circular hollows in a boulder; these cupmarks connect modern visitors to the beliefs and practices of Ireland's earliest inhabitants, who chose this specific stone and location for reasons we can only speculate about today.
