This circular earthwork, measuring 20 metres across its interior, consists of a raised platform about half a metre high, originally surrounded by a protective earthen bank. Today, only the western section of this defensive bank survives intact, standing roughly one metre tall, whilst the rest has been lost to time and the encroaching woodland.

The site appears to have been accessed via a narrow ridge from the north, where archaeologists have identified what may be the original entrance gap in the enclosing bank. The strategic positioning on elevated ground would have offered its inhabitants commanding views down the glen, providing both defensive advantages and oversight of the surrounding landscape. Such ringforts, known locally as raths, typically date from the early Christian period (roughly 500 to 1200 AD) and served as fortified homesteads for farming families of varying social status.

The interior space, now overtaken by tree stumps and thick undergrowth, would once have contained timber or wattle and daub buildings where daily life unfolded; cooking, crafting, and sheltering livestock. This particular site was documented during the comprehensive Archaeological Survey of County Donegal, conducted by Brian Lacey and his team in 1983, which catalogued field monuments from the Mesolithic period through to the 17th century. Though nature has largely reclaimed this ancient settlement at Cloghan More, its earthen footprint remains a tangible link to the people who once called this hillside home.
