It is the kind of site that appears on maps and in official registers without explanation, a named place that resists easy description precisely because the documentation has not yet caught up with it.

Enclosures of this type in Kerry can take many forms. Some are the remains of ringforts, the circular earthen or stone-walled farmsteads that dot the Irish countryside in their thousands and date broadly from the early medieval period, roughly 500 to 1200 AD. Others may be earlier, associated with Bronze Age settlement or ritual use of the land. Without more specific detail for this particular site, the type, date, and condition of the Ballynasare enclosure remain open questions. What is certain is that Ballynasare is a Gaelic place name, and Kerry as a county retains one of the densest concentrations of early archaeological monuments in Ireland, a consequence of both its long settlement history and the relative preservation afforded by its remoter townlands.
