Cartographers working on the Ordnance Survey six-inch maps of 1904 and 1935 recorded a circular enclosure roughly forty metres in diameter, marked with hachures, the short lines surveyors use to indicate a raised or defined edge. Today, nothing of it can be seen at ground level. The site is, in practical terms, invisible, known only through the memory of earlier map-makers and the faint persistence of local tradition.

Enclosures of this type are common across Cork and the wider Irish landscape, often the remains of ringforts, the circular earthen or stone enclosures that were the dominant form of rural settlement from the early medieval period onward. What distinguishes this particular example is what local tradition has attached to it: not a farmstead or a defended residence, but a mill. Mills were working parts of a rural economy, usually positioned near water, which the wet, low-lying ground here might help explain. Whether the enclosure ever functioned as a mill site, or whether an earlier enclosure was later reused or simply associated with one in local memory, cannot now be determined from what survives. The cartographic record at least confirms something was visible and distinct enough to map twice, three decades apart.
