The structure likely dates from the late medieval period, when tower houses were being built across Ireland by both Gaelic Irish families and Anglo-Norman settlers. These fortified residences served as symbols of power and provided protection during an era marked by territorial disputes and shifting allegiances.

The castle’s location in Corraunboy places it within the rich historical landscape of County Mayo, an area that witnessed centuries of conflict and change. During the medieval period, this region was controlled by various Gaelic septs, including the O’Malleys and the Burkes, who built numerous castles and fortifications throughout the county. The architectural style of the castle, typical of Irish tower houses, would have featured thick stone walls, narrow windows for defence, and multiple floors accessed by a spiral staircase built into the walls.

Today, the castle stands as a reminder of Mayo’s turbulent past, when local chieftains and lords required fortified homes to protect their families and assert their authority over the surrounding lands. Like many Irish castles, it likely fell into disuse following the Cromwellian conquest of the 1650s, when the traditional power structures of Gaelic Ireland were systematically dismantled. The ruins continue to offer visitors a tangible connection to the medieval world, where warfare, politics, and daily life intersected within these formidable stone walls.
