Though no trace of the medieval structure remains visible at ground level today, this location holds a forgotten piece of Irish history that connects the present landscape to its castellated past.

The castle itself appears in nineteenth century Ordnance Survey letters, those invaluable documents that recorded local history and folklore as surveyors mapped Ireland in the 1830s. O’Flanagan’s 1933 publication and Loeber’s 1988 work both reference these records, preserving the memory of a fortification that once stood here. Like many Irish tower houses and castles, Feddaun likely served as both a defensive structure and residence for a local family, though the specifics of its construction date and eventual destruction have been lost to time.

Today’s visitor will find only a residential property where the castle once stood, a common fate for many of Ireland’s lesser known medieval sites. The transformation from castle to bungalow represents a familiar pattern across the Irish countryside, where practical modern needs have replaced ancient stones, leaving only documentary evidence and place names to hint at what came before. The site was officially recorded in the Archaeological Inventory of County Offaly in 1997, ensuring that even without physical remains, Feddaun Castle’s existence remains part of the county’s documented heritage.
