Castle, Tinnaslatty, Co. Kilkenny
On a gentle, flat-topped bluff overlooking a small stream valley in County Kilkenny's rolling grasslands, there once stood a castle that belonged to the Viscounts Mountgarret.

The site offers expansive views along and across the valley, though today visitors will find no trace of the fortification that gave the area its local name, Castle Field. According to historical accounts from Carrigan’s 1905 work, the castle’s walls were already reduced to small fragments by around 1830, when the last remnants of the building were finally cleared away.
The castle’s exact location within Tinnaslatty townland remains something of a mystery. During fieldwork conducted in 1987, researchers identified a field immediately south of the County Laois boundary as the probable site, but no visible evidence exists at ground level to pinpoint precisely where the structure once stood. The field maintains its traditional name, preserving the memory of the vanished stronghold in local nomenclature if not in stone.
The site forms part of the wider estates that belonged to the Mountgarret viscountcy, with both the townland of Tinnaslatty and the now-lost castle falling under their ownership. While the physical structure has been absent for nearly two centuries, the location continues to intrigue those interested in Ireland’s medieval landscape, representing one of many lost castles that once dotted the countryside but now exist only in historical records and place names.
