This grass-covered hillock, roughly circular and measuring about 31 metres northeast to southwest and 28.3 metres northwest to southeast, stands as high as 5.25 metres where the natural limestone outcrop is exposed on its southwestern side. Whilst the mound may be partly natural, traces of stone and mortar visible in places tell a different story; this was once the site of a fortified structure that commanded the surrounding countryside.

Historical records place a castle here as early as 1574, according to Nolan’s 1901 account, and by the 1830s, when the Ordnance Survey Letters were compiled, it was already described as the ‘ruin of a castle’. The 1837 Ordnance Survey six-inch map shows a rectangular field subdivided by a north-south wall, labelled simply as ‘Site of Castle’. By the time the maps were revised in 1929, cartographers noted the castle site occupied a small mound on the eastern half of a raised rectangular area, carefully marked with hachures to indicate the elevation.

Today, visitors to this spot will find little to suggest its former importance beyond the impressive mound itself. The combination of natural limestone outcrop and human construction has created an intriguing archaeological feature; one that speaks to centuries of change in the Irish landscape. Compiled by the Galway Archaeological Survey at University College Galway, this site represents one of many lost castles that once dotted the Galway countryside, their stones long since repurposed or weathered away, leaving only earthworks and fragments to hint at their former glory.
