The site occupies a levelled area on the northern spur of a north-facing slope, with a stream running north to south at the base of the hill just to the east. Though the castle itself has long since vanished, careful observation reveals ghostly foundation outlines measuring approximately 15.4 metres from north to south and about 2 metres wide, though these traces become increasingly difficult to spot on the eastern side.

Known locally as ‘Caislean Cruinn’, this medieval fortification had already disappeared by the time the Ordnance Survey Letters were compiled in the 1830s. Writing in 1930, O’Flanagan noted that whilst nothing remained of the castle’s physical structure, its location was still well known to local residents; a testament to the enduring nature of place names and folk memory in rural Ireland. The name itself, which translates roughly as ‘Round Castle’, hints at what may have been an unusual circular design, though without excavation this remains speculation.

Today, visitors to the site need a keen eye and perhaps a bit of imagination to trace the subtle undulations in the grass that mark where walls once stood. The Archaeological Inventory of County Tipperary, compiled by Jean Farrelly and Caimin O’Brien in 2002, provides the most comprehensive modern assessment of the site, though ongoing research continues to add new details to our understanding of this lost stronghold. The peaceful pastoral setting gives little indication of the strategic importance this elevated position once held, commanding views across the surrounding countryside.
