Lannock Mill Weston · Hertfordshire · England

Lannock Mill is the surviving tower windmill at Weston. It is also known as Weston Windmill. Earlier windmills were shown in the area on Warburton's map of 1720 and Thomas Kitchin's map of 1749, but the present tower mill was built in 1860 by Richard Christy. Christy worked the mill until 1868, when his son Richard Christy junior took over.

The mill was a five-storey tower corn mill. The tower was 21 feet in internal diameter at the base, with walls two feet thick, narrowing to 15 feet at curb level. It rose 48 feet to the curb and more than 60 feet to the top of the cap finial. It had an ogee cap, an eight-bladed fantail, four single patent sails, and four pairs of millstones. The great spur wheel was of cast iron.

Richard Christy junior emigrated to America in 1882, and Thomas Sanderson took over the mill. He installed a steam engine as auxiliary power. The mill was badly damaged in a storm in the late 1880s, after which Course's of Biggleswade carried out repairs including new sails and cap. The steam engine was later replaced by a gas engine. Charles T. Stratton worked the mill from 1888 to 1929.

Lannock Mill continued to work by wind into the early 1920s and by engine until 1929. Over time it was stripped of its cap, sails, and machinery, leaving the tower standing. It was listed at Grade II in 1987 and remains a landmark west of Weston, surviving as a capless tower associated with The Mill on Hitchin Road.
