What makes it particularly striking is not just its scale but the layering of technologies, each generation of machinery either sitting alongside or quietly superseding the last.

The oldest element, recorded as a grist mill on the 1842 Ordnance Survey six-inch map, is a four-bay, three-storey structure built into the slope below the late-eighteenth or early-nineteenth-century house at the centre of the complex. Its wheel-pit still contains a breastshot suspension waterwheel, a type in which water strikes the wheel partway up rather than at the top or bottom, giving it a reasonable efficiency without requiring a great head of water. This particular wheel, made of cast iron with wooden buckets, has a diameter of just over six metres. Fragments of French burr millstone, a high-quality stone quarried near Paris and widely prized for flour milling, lie scattered outside. A second mill, attached to the north-west corner of the house and dateable to the mid or late nineteenth century, has the year 1917 plastered onto its west gable. This building tells its own compressed history: a waterwheel was eventually supplemented, and then replaced, by a water turbine, which was itself made obsolete when an oil-powered Stamford stone mill was installed. That Stamford mill still survives inside. The third mill, across the road and slightly to the north, was at some point converted into a grain-drying kiln, its interior fitted with ceramic kiln-tiles supported on iron beams. Water from the main millrace fed all three buildings in sequence, with tail races channelled beneath the road to keep the system connected. The whole complex was owned by the O'Shaughnessys, a branch of the same family associated with the Dripsey Woollen Mills elsewhere in County Cork.
