A restored six storey windmill that was built in 1877 to replace an earlier postmill. The six sailed windmill is in full working order. It was built by the Sanderson and Son company of Louth, and remained in operation until 1954, when it was converted to use engine power rather than wind.
Sibsey Trader Windmaill was fully restored in 1981, and is a Grade I listed building. There is a tea room on site, selling products made from the mill's own organic, stone-ground flours.
