That much is certain. Beyond the bare fact of its existence on the archaeological record, however, almost nothing has been formally published about it, which places it in an odd category: a monument that is known, classified, and mapped, yet effectively undescribed.

Enclosures are among the most common monument types in the Irish landscape. The term covers a wide range of features, from the circular earthen banks of a ringfort, which would have enclosed a farmstead in the early medieval period, to earlier prehistoric boundaries whose original purpose is harder to read. Clare is a county with a dense concentration of such remains, shaped partly by its geology and partly by the relatively light disturbance of some of its more marginal agricultural land. Ardkyle sits within that broader pattern, though what distinguishes this particular enclosure, its age, its form, its dimensions, whether any trace of it remains visible above ground, remains unrecorded in any accessible public source at this time.
