Marked on the 3rd edition of the Ordnance Survey 6-inch map, only the western section of this mysterious site was recorded, suggesting it may have once formed part of a much larger circular structure. Today, nothing remains visible above ground; the site has been completely absorbed back into the landscape, leaving only its cartographic ghost on old maps to hint at its existence.

The enclosure’s location in what was described as “good grass land” suggests this area has been valued for agriculture for centuries, perhaps even millennia. Such circular enclosures in Ireland often date from the Bronze Age through to the early medieval period and could have served various purposes: defensive ringforts, ceremonial spaces, or enclosed farmsteads. Without excavation, the true nature and age of the Dunross enclosure remains tantalisingly unknown.

This site was documented as part of the comprehensive Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983. The survey catalogued field antiquities spanning from the Mesolithic period right through to the 17th century, creating an invaluable record of Donegal’s archaeological heritage. While the Dunross enclosure may appear unremarkable to the casual observer today, its inclusion in both historic maps and modern archaeological surveys ensures this lost piece of Ireland’s past won’t be entirely forgotten.
