This earthwork mound, composed of earth and stone that has been partially quarried over the centuries, still retains traces of its defensive bawn wall, standing at roughly 0.8 metres high. The wall encloses an almost rectangular area measuring approximately 48.6 metres from north to south and 43.1 metres from east to west, giving visitors a sense of the castle’s original footprint.

The site holds particular historical significance as it was recorded during the Division of Connacht in 1574, when English administrators were carving up the western province amongst various claimants. This documentation places the castle firmly within the tumultuous period of Tudor conquest and plantation in Ireland, when traditional Gaelic lordships were being systematically dismantled and replaced with English administrative structures.

Intriguingly, two chamfered stones that appear to be fragments of a Romanesque arch can be found about 15 metres southeast of the main mound. These architectural remnants suggest there may have been an earlier ecclesiastical structure on or near the site, possibly predating the castle by several centuries. Such repurposing of religious sites for defensive structures was not uncommon in medieval Ireland, where strategic locations often saw successive waves of building and rebuilding as power changed hands between church and secular authorities.
