Ardaloo Castle, Ardaloo, Co. Kilkenny
Perched on a dramatic gravel ridge where the rivers Nore and Dinin meet in County Kilkenny, the lost castle of Ardaloo offers a tantalising glimpse into Ireland's medieval past.

The site commands spectacular views in every direction, with the ridge dropping steeply towards the river flood plain on its eastern and southern flanks, whilst sloping more gently down to the Nore on the western side. Today, much of the upper ridge has been transformed into pastoral farmland, but beneath the surface lies the remnants of what local tradition claims was once a monastic residence.
Writing in 1905, historian William Carrigan documented the castle’s impressive dimensions, noting that the structure measured approximately 11.3 metres by 9 metres externally, with walls of considerable thickness; the north wall alone was 1.5 metres thick, whilst the side walls, which once supported a stone arch over the first storey, reached an impressive 2.4 to 2.7 metres in width. The surviving fragment he observed stood 17 feet high and featured three narrow arrow loops, typical defensive features of medieval Irish architecture. Perhaps most intriguingly, Carrigan described a narrow passage between parallel walls extending roughly 27.5 metres south from the castle, connecting it to other buildings whose foundations remained visible in his time.
Whilst the castle appeared on the first Ordnance Survey map of 1839 and was still marked on revisions as late as 1946 to 1947, the structure has since vanished from view at ground level. Local lore maintains that the castle served the monks who attended the nearby church, situating it within Ireland’s rich ecclesiastical heritage. Though the stones have disappeared beneath centuries of soil and vegetation, the site remains a poignant reminder of the countless medieval structures that once dotted the Irish landscape, their stories preserved only in historical records and the memories of local communities.
