Sibsey Trader Windmill Sibsey · Lincolnshire · England

Sibsey Trader Windmill was built in 1877 by Sanderson and Son of Louth as a large six-storey tower mill, replacing an earlier post mill on the site. It was constructed as a wind-powered corn mill and became one of the last windmills built in Lincolnshire. Its six sails, slender tower, elaborate wrought-iron balcony, and fenland setting made it one of the county's most prominent tower mills.

The mill processed locally grown wheat, barley, and oats into flour and animal feed. Milling took place on the second, or millstone, floor, where grain descended from the bin floor through chutes into hoppers and shoes feeding the stones. The mill continued commercial operation until the 1950s, with wind-powered work ceasing in 1954. It then fell into disuse.

The mill was protected as a Grade I listed building in 1955 and is also scheduled. Restoration returned the mill to working order with engine-driven millstones in 1981, and the building came under the guardianship of English Heritage. It later operated as a heritage corn mill and became a member of the Traditional Corn Millers Guild. After gale damage in 2018, a further conservation project repaired and restored major wind gear. English Heritage completed a major conservation programme that restored the six sails, fantail, and cap, including the geared curb that allows the cap to rotate into the wind. Sibsey Trader Windmill now stands as one of the finest surviving Lincolnshire tower mills and a major fenland landmark.
