The mill race, the artificial channel cut to direct river water onto the wheel, has been dry for some time, leaving only the 2.6-metre-wide wheel pit and its bearing-stones along the southern elevation as evidence of the machinery that once turned here.

Corn mills like this one were a fixture of rural Irish life from the medieval period onward, processing grain into flour and meal for local communities. This example, built to a substantial four storeys, would have been a significant undertaking, and the attached miller's house to the east suggests it operated as a working household as well as an industrial site. The wheel pit's bearing-stones, the shaped stone supports that held the axle of the waterwheel in place, are among the more legible surviving details, offering a sense of the mechanical logic that once ran through the whole structure.
