Barnack Windmill Barnack · Cambridgeshire · England

Barnack Windmill stands on Stamford Road at Barnack. It is a five-storey tower mill built of coursed stone, with battered walls and small flat-arched openings. The listed description dates the mill to about 1797 and records it as a tower mill with a metal-clad ogee cap, remaining arms of the rails, part of the fantail, and a complete set of machinery intact.

The mill was built for wind-powered corn milling and continued in use until 1914. Photographic records show the mill after its working life, including views in 1932 and 1935 when it was disused with stocks and the original cap. Later views from 1950 show a similar condition, with part of one whip broken. Internal photographic records document important machinery including the brake wheel, great spur wheel, drive shafts, stone floor, stone nut, quant, and a pair of stones.

Restoration took place between 1959 and 1962. The mill was listed at Grade II in March 1962, and later photographs record it preserved with stocks and a replacement cap. The adjacent mill house was separately listed in 1982. Barnack Windmill now survives as a preserved stone tower mill with substantial internal machinery, retaining much of the technical character of a late eighteenth-century wind-powered corn mill.
