The site appears clearly on the 1840 edition of the Ordnance Survey 6-inch map, where it’s depicted as a long rectangular building measuring approximately 30 metres northeast to southwest and 8 metres northwest to southeast. The promontory itself spans roughly 30 metres by 20 metres, creating a natural defensive position above the river valley.

What makes this site particularly intriguing is its mysterious nature; despite being clearly marked on historical maps as “Castle (in ruins)”, there are no known historical references to a castle at this location. The structure has become so thoroughly reclaimed by nature that it’s no longer visible at ground level, hidden beneath centuries of vegetation and soil accumulation. This absence from historical records raises questions about when the building was constructed, who built it, and whether it was truly a castle or perhaps served another defensive or residential purpose.

The site was documented in the Archaeological Inventory of County Waterford, published by the Stationery Office in Dublin in 1999, with updates added as recently as December 2008. While archaeologists have identified its location and approximate dimensions from historical cartography, the ruins remain one of Waterford’s more enigmatic medieval sites, a phantom castle that exists more in old maps than in the visible landscape, waiting beneath the undergrowth for future investigation to reveal its secrets.
