While the second edition of the Ordnance Survey 6-inch map clearly marked a single-ringed enclosure at this location, no visible trace of the structure remains today. The topography itself, however, suggests this was likely an earthen construction, built to take advantage of the natural elevation and defensive position offered by the ridge.

These types of enclosures, common throughout Ireland, served various purposes throughout history; from defended farmsteads in the early medieval period to livestock corrals and even ceremonial spaces. The fact that it appears on historical maps but has since vanished from view isn’t unusual for earthen monuments, which are particularly vulnerable to agricultural activity, natural erosion, and the passage of time. Many such sites across Donegal have met similar fates, gradually melding back into the landscape until only the trained eye or archaeological survey can detect their presence.

The documentation of this site forms part of the comprehensive Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983. This ambitious project catalogued field antiquities spanning from the Mesolithic period through to the 17th century, creating an invaluable record of sites like the Ogherbeg enclosure that might otherwise be forgotten. Even when the physical remains disappear, these records ensure that the archaeological heritage of places like this Donegal ridge continues to inform our understanding of how past communities shaped and inhabited the Irish landscape.
