The enclosure at Ballyknockane, in County Tipperary, does not even offer that much. Set on low-lying pasture in a gently undulating stretch of countryside, it is completely invisible at ground level, leaving no trace for a visitor, or anyone else, to find.

The site was destroyed in the 1970s, a fate that befell a considerable number of Irish enclosures during that decade, when land improvement schemes and mechanised agriculture reshaped fields that had been largely untouched for centuries. Enclosures of this type, typically a roughly circular area defined by an earthen bank and ditch, were a common feature of early medieval Irish farming and settlement, serving variously as farmsteads, animal pounds, or defined boundaries around a dwelling. The Ballyknockane example was recorded by Stout in 1984, by which point its destruction was already a decade old. Jean Farrelly and Caimin O'Brien included it in the Archaeological Inventory of County Tipperary, ensuring it at least survived on paper, even if nothing of it remained on the ground.
