What makes it quietly notable is its former purpose: this was a fulling mill, a type of industrial building almost entirely absent from the popular image of rural Cork. Fulling was the process by which woven woollen cloth was cleansed and thickened, beaten repeatedly in water to mat the fibres together, and the mills that carried out this work were once a practical necessity in any sheep-farming district. That one existed here, on a narrow stream on the Beara Peninsula, points to a local textile economy that has long since vanished.

The remains date to the nineteenth century, and the engineering behind the site is still legible in the landscape. A mill race, cut directly into the rock, was used to divert water from the stream just north of the mill itself, channelling the flow to drive the machinery within. The building, though small, was carefully positioned to make use of the natural gradient of the bank. Access from the road passes over Aghakista Bridge, a narrow hump-backed structure with two semi-circular arches, which is itself a modest piece of vernacular stonework worth a moment's attention.

The site lies close to the road and the bridge provides the crossing point, though the ground around the stream bank is steep. The mill race cut into the rock is among the more concrete details still visible, offering a sense of the practical ingenuity involved in siting a small industrial operation on a fast-running upland stream.
