When antiquarian Fagan documented the site in the 19th century, he described a circular fort approximately 30 yards in diameter, defended by a parapet constructed from clay and stone. This modest defensive structure, typical of many early Irish ringforts, would have provided protection for a small farming community during troubled times.

What made this particular site especially intriguing was the presence of a substantial underground feature beneath the fort. Fagan reported discovering a cave system of considerable length, with at least 30 feet of accessible passage. The visible section varied between three and five feet in width, with a cramped height of just two to three feet; dimensions that would have required anyone exploring it to crawl on hands and knees. Such souterrains, as these underground passages are known, were common features of early medieval Irish settlements, serving as storage spaces, refuges during raids, or possibly holding ritual significance.

Despite its detailed recording in the Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983, modern surveys have failed to relocate this enigmatic site. The fort and its subterranean passages have seemingly disappeared, either destroyed by agricultural activity, collapsed through natural processes, or simply hidden beneath the overgrown pasture that now characterises the area. Its absence serves as a reminder of how many archaeological features recorded by earlier generations have been lost to time, leaving only their descriptions as testament to what once existed in the Irish countryside.
