Not a wall, not a foundation, not so much as a scatter of dressed stone. The site of Curragour Mill is, in the most literal sense, an absence.

The mill was built in 1672 and stood long enough to be recorded on Phillips's map of 1685, where it appears at the western edge of Curragour Falls, and again on Christopher Colles's 1769 "Plan of the city and suburbs of Limerick", a document now held in the British Library. By the time the Ordnance Survey produced its six-inch map in 1840, the mill was still annotated on the west bank of the Shannon, with a second mill shown directly opposite on the east bank. The end came by fire, and whatever remained of the structure was cleared away by 1858, according to O'Flaherty's account and the earlier record of Fitzgerald and McGregor. In 1998, archaeologist Edmond O'Donovan, working under licence on behalf of Margaret Gowen, opened a single ten-metre test trench at the manhole shaft on Clancy's Strand, close to where the mill once stood. What he found beneath the surface was a nineteenth-century soil profile sitting over natural ground, interpreted as material laid down when the road alongside the Shannon was constructed. The ground had simply been built up and moved on.

Clancy's Strand runs along the river in the King's Island area of Limerick city and is easily accessible on foot. Curragour Falls, the natural feature that would have provided the mill's water power, is still visible from the riverbank, particularly in periods of lower flow when the rocky bed of the Shannon is more exposed. There is nothing to mark the mill's location, no plaque or outline on the ground, which is in some ways the whole point. The 1840 OS six-inch maps, freely available through the OSi historical viewer online, show the mill symbol clearly enough that you can orient yourself to the spot and understand exactly what is not there.
