Locals know it as Manor Mill, a name that points directly to its origins on land belonging to the Earl of Kingston. The building itself is substantial and plain, constructed in random-rubble limestone with a hipped slated roof and a central valley, gabled projections breaking the roofline on the north and east sides. The north elevation runs to three bays, the east to four, the window openings small and functional. It is the kind of structure that reads as entirely purposeful, with nothing wasted on ornament.

Built around 1800, the mill drew its water from the Gradoge via a millrace that tapped the river roughly half a kilometre to the west, with a tail race, the channel that carries water away after it has done its work turning the wheel, running some 0.8 kilometres eastward through the north end of the town. The 1842 Ordnance Survey six-inch map shows the whole arrangement clearly, even if neither the mill nor the race is named on it. By the 1905 edition, the map labels it plainly as a corn mill and adds the word "Disused", which tells its own story about the pace of decline in rural milling. The building did not stand idle for long, though. In the 1930s, Mitchelstown Creameries took it over for the manufacture of butter boxes, repurposing its solid walls and generous floor space for an entirely different kind of food production. It functions today as a store. During sewerage works in the town, an arched section of the original tail race was exposed beneath the road surface, a reminder that the infrastructure of the mill runs deeper into Mitchelstown's fabric than the visible building suggests.
