That much seems certain. What is less certain is precisely where it stood, and almost nothing of it survives today, at least nothing that has been positively identified. It is the kind of structure that leaves only the faintest impression on the historical record, easy to overlook precisely because windmills were, in their time, entirely ordinary features of the working landscape.

The source for this particular mill is Francis Elrington Ball, whose 1906 historical survey of County Dublin noted its existence in the Kilmainham-Islandbridge area and placed it as post-1700 in date. Ball was a careful chronicler of Dublin's built environment, and his passing reference suggests the mill was real enough, even if he could not pin it to a precise location. Windmills of this period were typically tower mills or post mills, used for grinding grain or, in some urban and peri-urban contexts, for pumping water. The Kilmainham area in the eighteenth century was not yet fully absorbed into the city and retained a mixed character of institutional buildings, open ground, and small-scale industry. A windmill would have fitted naturally into that landscape, catching the westerly winds coming in from the Liffey valley.

There is, practically speaking, nothing to visit here in any conventional sense. No structure has been confirmed, no plaque marks the spot, and the general area has been substantially altered by later development. What the site represents is more of a research curiosity than a destination, the kind of detail that rewards those already exploring the broader Kilmainham and Islandbridge area for other reasons. Visitors interested in Dublin's industrial and milling history might treat Ball's reference as a prompt to look more closely at the streetscape and townland patterns of the area, where occasional anomalies in plot boundaries or place-name evidence sometimes hint at long-vanished structures. Local archives and the historic Ordnance Survey maps of Dublin, available through the National Library and various online repositories, would be the logical next step for anyone hoping to narrow down the location further.
