This rectangular enclosure measures 66 metres from north to south and 71.4 metres from east to west, defined by an earthen bank that rises 0.7 metres above the surrounding field. Along the eastern side runs an internal fosse, or defensive ditch, carved 0.4 metres deep into the ground; a common feature of Anglo-Norman fortifications that would have once held water to enhance the site’s defences.

The enclosure has two entrance points along its northern edge, suggesting this was the primary approach to whatever structure once stood within. At the heart of the site sits a circular stone foundation, 5.6 metres in diameter and standing just 0.3 metres high, likely the remains of a tower house or similar defensive dwelling. These moated sites typically date from the 13th to 14th centuries, when Anglo-Norman settlers established fortified homesteads throughout Ireland, combining agricultural functions with defensive capabilities.

Time and agriculture have taken their toll on the monument; a later stone field boundary now cuts directly through the southeastern corner of the site, a reminder of how medieval landscapes have been continuously reshaped by centuries of farming. Despite these intrusions, the site remains a tangible link to Mayo’s medieval past, when such moated enclosures dotted the countryside, serving as both status symbols and practical fortifications for the Anglo-Norman colonists who sought to establish themselves in the Irish landscape.
