This rectangular structure, measuring eight metres in length and five metres in width, consists of collapsed drystone walls that have surrendered to centuries of Irish weather. The site appears on old Ordnance Survey maps as the ‘Ruins of Castle Freeky’, a name that hints at local folklore or perhaps a corruption of an older Irish place name.

What remains today offers few clues to its original purpose or appearance. The walls, built without mortar in the traditional drystone technique common to western Ireland, have tumbled inward, leaving no visible doorways, windows, or other architectural features that might help date the structure or reveal its function. Its position within the ringfort suggests it may have served as a later addition; perhaps a small tower house, domestic building, or agricultural structure built long after the ringfort itself fell out of use.

The site at Cashlaun Feecul represents one of countless unnamed and undated ruins that dot the Irish landscape, each a fragment of the complex layers of habitation that have shaped rural Galway over millennia. While Castle Freeky may lack the grandeur of better preserved castles, its very obscurity and the mystery of its peculiar name make it a compelling reminder of how much local history remains unwritten, surviving only in crumbling stones and fading maps.
