Rock art, Carrowreagh or Craignacally, Co. Donegal

This smooth rock outcrop, which slopes gently at 12 degrees to the southeast, bears an intricate collection of carved markings that offer a tantalising glimpse into Ireland's distant past. The carvings include approximately eight large, roughly hewn cup marks; two possible groove marks; and most notably, a prominent cup mark surrounded by five weathered rings that, whilst not perfectly circular, remain clearly visible despite centuries of exposure to the elements.

The centrepiece of this ancient artwork is particularly intriguing: a rather large central cup mark featuring what archaeologists describe as a 'tail', surrounded by the five rings mentioned above. Additionally, the rock face displays a cup mark with traces of two rings and an impressive collection of 32 smaller cup marks, most of which cluster to the northeast of the main five-ringed carving. These miniature cups add an extra layer of complexity to what appears to have been a significant prehistoric site.

Archaeological surveyor Martin Van Hoek documented this site in 1988, noting that vegetation had begun to overtake the carvings. In an effort to protect these ancient markings from further deterioration, Van Hoek covered the rock art with turf after completing his survey. This protective measure helps preserve one of Donegal's lesser-known archaeological treasures; a stone canvas that connects modern visitors to the artistic expressions of Ireland's prehistoric inhabitants, created perhaps 4,000 to 5,000 years ago during the Neolithic or Bronze Age periods.
