Croxley Green Windmill Croxley Green · Hertfordshire · England

Croxley Green Windmill was built around 1860 as a tower corn mill. It stood as a five-storey tower with a stage at second-floor level and an internal diameter of 22 feet at ground level. The mill had a boat-shaped cap, turned by a fantail, and four patent sails driving three pairs of millstones.

The first recorded miller was Isaac Watts in 1861. Later millers included Philip Howard, J Batchelor, William Caldwell, Ephraim Holloway, and Hannah Holloway. The mill worked by wind through the nineteenth century until its sails were blown off in the 1880s. From 1886 it continued in use with steam power only, showing the shift from wind to auxiliary mechanical power in its final working phase.

The mill was last used to grind wheat in 1899. After milling ended, the building continued in practical use as a saw mill and turnery. By the 1930s it had been adapted to agricultural and domestic ancillary uses as a chicken house and pigeon loft. During the Second World War the tower was used as an Air Raid Precautions observation post, with an air raid siren mounted on the structure.

The former tower mill was converted to residential accommodation in the 1960s. It was listed at Grade II in 1973. Later planning material records the significance of the surviving tower mill, its arched openings, and former balcony arrangement, and notes the suburban setting that developed around what had once been a more detached mill site. The building survives as a converted listed tower mill at Croxley Green.
