No earthwork, no trace of a wall, no depression in the ground that might cause a passing walker to pause and wonder. Yet for a brief window in the historical record, something was there, circular in form, its outline captured by the surveyors who mapped this part of Ireland in 1841 and 1842.

The Ordnance Survey's first edition mapping of Ireland, carried out in the 1830s and 1840s, was remarkably thorough, and its surveyors noted features on the landscape that were already ancient and decaying. Circular enclosures of this kind are a common enough presence in the Irish archaeological record; they are generally understood as the remains of enclosed farmsteads or settlement sites, sometimes dating back to the early medieval period, constructed from earthen banks or stone walls that defined a domestic space. Whatever stood at Cloonametagh was recorded on that first map, then absent from the later edition, suggesting it had either collapsed entirely or been levelled in the intervening decades, perhaps cleared for agricultural use. No surface trace now survives. The site is known primarily from C. Toal's North Kerry Archaeological Survey, published in 1995, which catalogued it alongside more than a thousand other features across the region.
