Description
Flint Mill and attached mill-race structures is a water mill that has been converted into a house. It is marked as Flint Mill Farm on the Ordnance Survey map and dates back to 1722, with alterations made in the 20th century. The building is constructed from coursed, squared magnesian limestone and features a stone slate roof. It stands two storeys high with a basement and has a layout of five bays by three bays.
The entrance front includes a quoined, segmentally-arched doorway located to the right of the center, flanked by circular windows (oculi). There are four flat-arched windows on each floor, all fitted with 20th-century casements, and a small eaves stack on the left side. The rear of the building, which faces the River Wharfe, has a large undershot waterwheel on the left. This waterwheel has eight wooden spokes attached to a cast-iron rim and iron blades. The basement features various small casements, while the ground floor has three square-headed and two round-headed windows, all with 20th-century casements. The first floor has four 20th-century casements under flat arches, and there is an eaves stack on the right.
On the left side of the building, there are three round-arched openings at the basement and ground floors, with matching windows above on the first floor that have casements with glazing bars. Inside, the basement contains a large cast-iron flywheel and crown wheel, with a massive vertical wooden shaft that rises to the ground floor, where another crown wheel and associated shafting can be found.
The external mill-race structures are built from gritstone and include a dam wall with an inlet for the mill race, along with a race that features stepped troughs to create a fish ladder. There is also a third bypass channel with a concrete-filled inlet, flanked by one triangular and one rounded cutwater. Originally built as a corn mill, it was converted in 1774 by Leeds Potteries to grind flints using German stones, before reverting to corn milling in 1878 until its final closure around 1950.
