Enclosures of this kind appear across Ireland in considerable variety. Some are the earthen or stone ringforts of the early medieval period, domestic settlements enclosed for security and status. Others are earlier, associated with Bronze Age or Iron Age activity, or later, connected with field systems or ecclesiastical use. The name Carrownakilly derives from the Irish, with "carrow" typically indicating a quarter-land division, an old unit of land measurement used in the Gaelic system. Whether the enclosure relates to the agricultural history of that division, or predates it entirely, is the kind of question that the surviving record does not yet answer.
