The site, which appeared as a single-ringed enclosure on the 2nd edition of the Ordnance Survey 6-inch map, has left no visible traces despite the area's good soil cover and its current use as rough grazing land. The gentle topography of the ridge would have made it an ideal location for such a structure, offering both defensive advantages and visibility across the surrounding countryside.

This lost enclosure represents one of many archaeological features documented across County Donegal that have succumbed to time, agriculture, and the elements. The information about this site comes from the comprehensive Archaeological Survey of County Donegal, compiled in 1983 by Brian Lacey and his team of researchers. This survey catalogued field antiquities spanning from the Mesolithic Period through to the 17th century, creating an invaluable record of sites that might otherwise be forgotten.

Without physical remains to study, archaeologists must rely on historical maps and written records to understand what once existed at Drumstevlin. The earthen nature of the enclosure, whilst typical of many Irish archaeological sites, made it particularly vulnerable to erosion and agricultural activity. Such enclosures often served various purposes throughout history; as defended farmsteads, livestock corrals, or ceremonial spaces, though without excavation or surviving features, the specific function of this particular site remains a mystery.
