It is the kind of monument that appears on maps as a symbol, a polygon, a dot, without the accompanying words that might explain what it once was or who made it. Enclosures in Ireland range enormously in character and date, from the low earthen banks of early medieval ringforts, which served as farmsteads for a family and their livestock, to the drystone cashels of the Atlantic seaboard and the ceremonial or funerary enclosures of prehistory. Which category Parkboy falls into remains, for now, an open question.

The townland name itself offers a small clue about the landscape, if not the monument. "Parkboy" likely derives from the Irish, possibly incorporating "buí", meaning yellow, applied perhaps to a field or a stretch of boggy ground nearby. Kerry is a county where the ground beneath the turf frequently conceals earthworks that have survived simply because the land was never intensively ploughed. That pattern of survival is common across the west of Ireland, where monument densities can be high even where the documentary record is thin. Without further detail, the enclosure at Parkboy joins a long list of features that are known to exist, protected in principle, but not yet fully drawn into the written record.
