According to his 1889 records, this ancient stone fort featured a small diameter but remarkably tall walls; a rather unusual combination for such structures. Despite attempts by later archaeologists to locate this intriguing site, neither the precise location of Doongonmoyle nor the cashel itself could be traced, leaving Kinahan’s discovery something of a mystery.

The search wasn’t entirely fruitless, however. At nearby Doongonigle, situated along the shores of Mulroy Bay, investigators discovered what might be related defensive earthworks. The narrowest section of a promontory here shows what appears to be a bank and fosse arrangement, though whether these features are entirely natural or were enhanced by human hands remains uncertain. The heavily wooded nature of the area makes proper archaeological assessment challenging, leaving questions about whether this might be connected to Kinahan’s lost cashel.

This information comes from the comprehensive Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983. The survey, which catalogues field antiquities from the Mesolithic period through to the 17th century, represents one of the most thorough archaeological records of the county. The entry for this particular site, located in the townland of Woodquarter, exemplifies the ongoing detective work required to piece together Ireland’s ancient landscape from historical records, place names, and physical remains.
