The mill that once sat above them is now a roofless, overgrown ruin on the western bank, but enough survives to make clear this was once a substantial industrial complex: a main rectangular building, a five-storey mid-nineteenth-century wing making the whole plan L-shaped, a separate three-storey store house to the north-northwest with a curved corrugated iron roof, and a two-storey residential house clinging to the top of a steep scarp at the northwest corner. The wheel-pits themselves still contain iron axles, flaunches (the flanged collars that fixed the wheel to its axle), and the slim iron arms of both wheels, the northern pit having held a twelve-foot-by-eight-foot undershot waterwheel and the southern a slightly different five-foot-by-twelve-foot undershot wheel. An undershot wheel is driven by the flow of water passing beneath it rather than falling over it from above, and here that flow was managed by a weir built across the river to feed a headrace, the channel directing water to the wheels.

The mill was erected in 1750, and by the time the first detailed Ordnance Survey maps were made in 1842 it was operating as a flour mill. Its later history involved at least two significant shifts. Maurice Hickey enlarged the complex in the late nineteenth century, but the mill then sat idle for over a decade, from 1890 to 1903, before T. W. Priestly converted it into woollen mills. By 1905, the Ordnance Survey was recording it under that new designation. The change from flour to wool reflects a broader pattern in Irish milling history, where falling grain prices and rural depopulation in the late Victorian period left many corn mills unviable, and entrepreneurs sometimes found a second life for the buildings in textile production.
