It has not turned in a very long time. The wheel, roughly four and a half metres in diameter, bears an iron plaque reading "W.S. Winey, Cork", and its wooden buckets have long since decayed. Above it, inside the ivy-clad shell of a three-storey mill with a collapsing slate roof, a vertical wooden shaft carries a painted date: 1816. The gearing that once transferred the wheel's motion upward through the building, a great spur wheel with wooden clasp-arms, a pinion shaft, bevelled gear wheels at successive floors, remains largely in place, though everything is in an advanced state of collapse. Scattered in the rubble nearby are the stone-nut, the spindle, and a French-burr bedstone, the hard-wearing millstone of a type traditionally imported from quarries near Paris.

By 1837, when the topographer Samuel Lewis compiled his account of the area, the operation was substantial enough to warrant description as the "extensive boulting-mills of Messrs. Haines and Smith", employing twenty-five people. Boulting mills were used to sift and grade flour after grinding, so the site was not simply a grinding point but a more complete processing facility. Attached to the south wall of the main building is a roofless grain-drying kiln, its ceramic tile floor still partially visible overhead and the lower courses of its central furnace still standing, a reminder that grain arrived here damp and had to be dried before it could be milled reliably. A four-storey extension with brick-arched window openings and a partly surviving slate roof abuts the west wall, suggesting the operation expanded at some point, though no machinery survives inside it.
