Nothing remains above ground to confirm a medieval structure ever existed here, yet the location is thought to correspond with a mill recorded in the Down Survey, the remarkable mid-seventeenth-century mapping project commissioned by the Cromwellian administration to catalogue confiscated Irish land. That a mill should be noted and then effectively vanish, leaving no stone or earthwork visible at the surface, is not unusual for medieval industrial sites in Ireland, but it gives the place an odd quality, a kind of absence defined by what the documents suggest rather than what the ground confirms.

The Down Survey, carried out in the 1650s under the direction of William Petty, was one of the most ambitious cartographic undertakings of its era and remains a significant source for understanding land use and settlement in pre-Williamite Ireland. Its mention of a mill at or near this location points to a working agricultural economy in the area during the medieval period, when watermills were central to grain processing across rural Ireland. By the eighteenth century, milling activity had evidently continued or resumed, since a corn mill appears on the Ordnance Survey six-inch map of the area, a different structure from any medieval predecessor, and one that represents the later phase of the site's industrial life. Corn mills of that period typically harnessed a millrace or diverted stream to drive a horizontal or vertical wheel, though none of this machinery survives here to be examined.
