This oval enclosure, measuring 45 metres from northeast to southwest and 32.5 metres from northwest to southeast, occupies a commanding position over the surrounding landscape. The site's edges are defined by a distinct scarp, though modern roads have encroached upon its southern and western boundaries over the years.

The elevation of this ancient fortification varies considerably around its perimeter; rising just 0.8 metres above the surrounding land on the northeastern side, whilst the southwestern edge stands an impressive 3.2 metres high. This difference in height likely reflects both the natural topography and deliberate defensive modifications made by its builders. The choice of location speaks to the strategic thinking of its creators, who selected this prominent spot on good agricultural land where they could survey and potentially control the surrounding area.

Though its exact age and original purpose remain subjects of archaeological interest, the site represents one of many such enclosures dotting the Irish landscape, each telling part of the story of how communities organised and defended themselves in ancient times. The fort was documented as part of the comprehensive Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983, which catalogued field antiquities from the Mesolithic period through to the 17th century.
