Marked as ‘Carn’ on the first edition of the Ordnance Survey 6-inch map, this site appears to have vanished from the landscape, leaving behind only tantalising hints of its former presence. What remains today is a modest section of rock outcrop, measuring roughly 2 metres by 1 metre, sitting on what local surveys describe as good quality land.

The site’s mysterious disappearance raises intriguing questions about the nature of Ireland’s archaeological record. Cairns, which are stone monuments typically built as burial sites or territorial markers, were common throughout prehistoric Ireland. The fact that this one was significant enough to merit inclusion on early OS maps yet has since been lost suggests it may have fallen victim to agricultural improvement or stone robbing, a common fate for many of Ireland’s ancient monuments during the 18th and 19th centuries.

This elusive cairn was documented during the comprehensive Archaeological Survey of County Donegal, conducted by Brian Lacey and his team in 1983. Their work, which catalogued field antiquities from the Mesolithic period through to the 17th century, represents one of the most thorough archaeological inventories undertaken in Ireland. Though the original cairn may be gone, its inclusion in both historical maps and modern surveys ensures its place in the archaeological record of Donegal, serving as a reminder of how much of our built heritage exists only in memory and documentation.
