There is nothing to see now, no millstone propped against a wall, no ruined gable, no tell-tale channel where water once ran. The site has been entirely absorbed into the built environment, which makes it an oddly instructive kind of place, one where the absence itself is the point.

The structure appears by name on the Ordnance Survey six-inch map of 1840, recorded as Shanwillen Old Mill, suggesting it had already acquired that designation of age well before the nineteenth century was out. By the time the revised OS six-inch map was produced in 1924, it was still depicted, a rectangular building measuring approximately fifteen metres on its north-east to south-west axis and ten metres across. That the mapmakers continued to record it into the twentieth century indicates it retained some physical presence, or at least a recognisable footprint, long after it had ceased to function. At some point after 1924, it was demolished, and subsequent residential development removed any remaining evidence. The site was compiled for the record by Denis Power in 2013.

For anyone inclined to look, Dooradoyle is a suburb that has expanded rapidly in recent decades, and the area around the former mill is now thoroughly residential. There is no access point to speak of, no heritage marker, and no visible archaeology. The value of knowing the site exists is largely cartographic; comparing the 1840 and 1924 OS maps against a modern satellite image gives a clear sense of how completely the landscape has been redrawn. The 1840 name, Shanwillen, likely preserves an older Irish place-name that predates the mill itself, and that thread of linguistic continuity is now the only trace worth following.
