Where the first and second editions of the Ordnance Survey 6-inch maps once marked a single-ringed fort, nothing remains visible today. The site sits on good quality land, though its elevated and exposed position would have left any settlement here at the mercy of Atlantic weather systems sweeping across the county.

This vanished enclosure represents one of countless ringforts that once dotted the Irish countryside; circular defensive structures that served as fortified homesteads for farming families from the early medieval period onwards. The complete disappearance of the Kildoney Glebe fort isn’t unusual; centuries of agricultural improvement, land clearance and changing farming practices have erased many such monuments from the physical landscape, leaving them to exist only in the meticulous records of 19th-century cartographers.

The site was documented as part of the comprehensive Archaeological Survey of County Donegal, compiled in 1983 by Brian Lacey and his team of researchers. This ambitious project catalogued the county’s archaeological heritage from the Mesolithic period through to the 17th century, capturing details of monuments both surviving and lost. For the Kildoney Glebe enclosure, the survey could only confirm what the old maps suggested: that a fort once stood here on this windswept patch of good land, before time and human activity conspired to remove all trace of it from view.
