That gap itself is quietly telling. Ireland's landscape is scattered with enclosures of various kinds, from early medieval ringforts, which were typically circular earthen banks enclosing a farmstead, to later ecclesiastical or field enclosures, and without further detail it is not possible to say with certainty which tradition this one belongs to. What is clear is that it has been identified, mapped, and assigned a monument record, which means someone, at some point, considered it significant enough to preserve in the national inventory.

The townland name Carrownakilly derives from the Irish, most likely a form of "Ceathrú" meaning a quarter, combined with a second element that may relate to a personal name or a local feature. Clare is a county of considerable archaeological depth, from the Burren's prehistoric tombs and cashels to early Christian sites along the Shannon, and enclosures in this part of the west of Ireland frequently date to the early medieval period, roughly 500 to 1200 AD, when enclosed farmsteads were the dominant form of rural settlement across the island. Whether this particular enclosure fits that pattern remains, for now, an open question.
