While archaeologists have documented its existence, the site doesn’t appear on either the first or second editions of the Ordnance Survey 6-inch maps, suggesting it had already faded from local memory or visibility by the time those surveys were conducted in the 19th century. What we do know is that it once stood on mixed pasture land, commanding views northward across the Finn Valley; a strategic position that would have offered both defensive advantages and control over the surrounding countryside.

The lack of physical evidence makes dating and interpreting the enclosure particularly challenging. These types of earthwork enclosures in Ireland could date from various periods, from the Bronze Age through to the medieval period, and served multiple purposes: defensive ringforts, cattle enclosures, or ceremonial spaces. Without excavation or more detailed survey work, the Drumavish enclosure keeps its secrets, though its elevated position overlooking the valley suggests it held some importance for the community that built it.

This information comes from the comprehensive Archaeological Survey of County Donegal, compiled in 1983 by Brian Lacey and his team of archaeologists. Their work catalogued field antiquities across the county spanning from the Mesolithic period right through to the 17th century, providing an invaluable record of sites like Drumavish that might otherwise be completely forgotten. Even though the enclosure itself has vanished from the landscape, its inclusion in this survey ensures that future generations know something once stood here, watching over the Finn Valley.
