The structure appeared on the 1837 Ordnance Survey six-inch map as a square building, marked simply as “Ruins” in the distinctive typeface the OS reserved for antiquities. Today, nothing remains visible above ground, leaving the exact nature and age of this castle a mystery.

The site’s history is intertwined with that of Lissard House, which stood nearby until it was demolished in the 1950s. The castle ruins would have been a familiar sight to residents and visitors of the house, a tangible link to the area’s medieval past. Local tradition holds that this was indeed an ancient residence, though without archaeological investigation, it’s impossible to determine whether it was a tower house, a fortified dwelling, or some other type of defensive structure typical of medieval Ireland.

What makes Lissard particularly intriguing is how completely it has vanished from the landscape. Unlike many Irish castle sites where at least some stonework survives, here the passage of time has erased all visible traces. The site serves as a reminder of how many historic structures have been lost across the Irish countryside; places once deemed significant enough to merit special notation on early maps, now existing only in historical records and local memory.
