What makes the site unusual is not simply its age but its variety: by the mid-nineteenth century this single riverside lot was operating both corn and tuck mills, the latter being fulling mills used in the finishing of woollen cloth, a process that required the same reliable flow of water that grain milling depended upon. The Ordnance Survey six-inch map of 1842 records them plainly as "Tuck and Corn Mills", suggesting a small industrial cluster that would once have been central to the agricultural and textile economy of the surrounding area.

The three structures each tell a slightly different story. The largest is a gabled five-bay, four-storey building, with later additions to the rear giving it an L-shaped plan; its wheel pit, measuring 2.1 metres wide, runs along the south-west elevation and drew water directly from the river to the south. Immediately to its south stands the remnant of a second mill, now reduced to a single surviving gable with its own external wheel pit of 1.5 metres; both mills shared a mill race, the channel cut to direct water onto the wheel. The third building, to the west and now heavily overgrown, is the most substantial in footprint, running to eight bays, three storeys, and six bays deep in a U-shaped plan. Its wheel pit is the widest of the three at 2.25 metres, and this building served a quite different industrial purpose: during the nineteenth century it operated as a barytes mill. Barytes, or barium sulphate, was mined in parts of west Cork and processed for use in paint, paper, and various industrial applications, making this westernmost ruin an indicator of the region's involvement in mineral extraction rather than agriculture or textiles.
