Carnasserie Rock Art Excavation 2023
Why excavate rock art?
During the Neolithic and Bronze Ages, people created thousands of carvings on rocky outcrops throughout Kilmartin Glen. Most of these carvings consist of dots, circles, and lines, commonly known as cup and ring markings. They range from simple clusters of cup marks (circular hollows) to complex designs, including some of Scotland's largest and most elaborate rock art panels.
Rock art in the Kilmartin area is part of a broader phenomenon. Similar carvings are found throughout Scotland, northern England, Wales, and Ireland. But why did people put so much effort into creating these symbols? Exactly how old are they, and what was their significance? These questions have been asked ever since rock art was first recognised over a century ago, and hundreds of explanations have been suggested.
Until recent years, there has been a tendency for cup and ring markings to be studied, quite literally, as symbols set in stone. Emphasis was placed on recording and illustrating the markings themselves, rather than examining their wider context or even how they were made. While this has led to a valuable visual record, it has sometimes resulted in the carvings being viewed in isolation from their wider context, the surrounding landscape. This kind of rock art has also proven to be notoriously difficult to date. Fortunately, new approaches to fieldwork and recording are now transforming our understanding.
Between 2004 and 2009, excavations at Torbhlaren in nearby Kilmichael Glen (conducted by the University of Southampton) and Ormaig (in collaboration with Kilmartin Museum/University of Southampton) revealed remarkable insights into the creation and use of rock art.

Both sites revealed hammerstones that prehistoric people used to carve the rocks. At Torbhlaren, thousands of pieces of broken quartz and modest quantities of worked flint and Arran pitchstone were also discovered. These findings significantly changed our understanding, as they highlighted the methods used to create rock art. They serve as a crucial reminder that the symbols we see on the rocks were produced through deliberate and sustained actions, resulting in dust and percussive sounds. The use of quartz is particularly interesting because this material has unique properties. Its semi-translucent crystals sparkle when they catch the light and produce an eerie glow when struck together in the dark.

Rock art is incredibly difficult to date, and Torbhlaren is one of the few rock art sites in the landscape to have produced radiocarbon dates. These suggest that the cup and ring markings were made there through the Later Neolithic and the Bronze Age (c.3000 to 1200 BC).
Excavations elsewhere in Scotland and northern England have also added fresh, and often unexpected, insights into rock art. But many questions remain! Given the abundance of rock in the Kilmartin area and its proximity to other kinds of monuments, further investigations are essential. The Regional Research Framework for Argyll has identified rock art as a key subject for research:
“How does cup-and-ring rock art fit into our overall understanding of the nature of society, beliefs, and external contacts in Argyll and Bute? Currently it tends to be studied in its own right, but it needs to be situated within Late Neolithic practices (and more dating evidence for its creation is needed)”
