The structure consists of an oval enclosure measuring 14.5 metres across its northwest to southeast axis and 17 metres from northeast to southwest. What remains today is a substantial stone wall, roughly 2.05 metres wide and varying in height from half a metre to a full metre, constructed from massive stone blocks that are now partially concealed beneath a covering of heather and bog vegetation.

The cashel’s most intriguing feature is an internal dividing wall that runs north to south across the site, splitting the interior space into unequal sections; one third to the east and two thirds to the west. This partition wall, measuring 0.8 metres wide and 0.5 metres high, has partially collapsed over the centuries but still clearly delineates the two areas. A gap of 2.15 metres on the southeastern side likely marks the original entrance, offering a tantalising hint at how the site’s ancient inhabitants would have accessed this fortified space.

The location itself speaks to the challenging conditions faced by those who built and occupied this cashel. Situated on poor, boggy land dotted with rock outcrops, the site would have required considerable effort to construct and maintain. Despite the harsh environment, the enduring presence of these stone walls demonstrates the skill and determination of the builders. This archaeological treasure was documented in the comprehensive Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983, providing valuable insights into the county’s rich heritage spanning from the Mesolithic period to the 17th century.
