These circular enclosures, known in Irish as raths, were the standard farmstead of early medieval Ireland, typically consisting of an earthen bank and ditch enclosing a family's dwelling and outbuildings. Tens of thousands once existed across the island; several thousand survive in some form. This one carries a place name that offers its own quiet curiosity. Knocknahaha derives from the Irish, most likely containing the element for hill and possibly a reference to a personal name or local feature long since dissolved from living memory.

Beyond its location in Kerry and its classification as a rath, the detailed record for this particular site has not yet been made available through public channels, which places it in a category occupied by a surprising number of Irish monuments: known, mapped, classified, but not yet fully documented in accessible form. What can be said is that ringforts of this type generally date from roughly the sixth to the twelfth century, and Kerry's landscape holds a particularly dense concentration of them, reflecting the county's significance during the early Christian period when this form of enclosed settlement was at its height. The surrounding terrain, typical of much of Kerry, would have offered both the elevated ground favoured for such enclosures and the agricultural land necessary to sustain the families who built them.
