What remains today is modest; just 16 metres of the south-southeast section of an earthen bank that once formed part of a much larger defensive structure. The surviving portion still manages to tell its story through its physical features, rising one metre high on its internal side before dropping dramatically 3.6 metres to the base of what archaeologists identify as an external fosse, or defensive ditch.

This ringfort, known locally as a rath, represents one of thousands of similar structures that once dotted the Irish landscape between the early medieval period and the 17th century. These circular or near-circular enclosed settlements served as fortified homesteads for farming families, offering protection for both people and livestock. The strategic placement on the south-sloping side of Bredagh Glen would have provided natural drainage whilst offering views across the surrounding landscape, typical considerations in ringfort construction.

The site’s documentation comes from the comprehensive Archaeological Survey of County Donegal, compiled in 1983 by Brian Lacey and his team of archaeologists. Their work catalogued field antiquities spanning from the Mesolithic period through to the 17th century, preserving crucial information about sites like Lithmore that might otherwise be lost to time and vegetation. Though nature has largely reclaimed this ancient settlement, the surviving earthwork continues to mark where a community once lived, farmed, and defended their small corner of medieval Donegal.
