Over the years there have been four windmills in and around Cranbrook of which only the Union Mill survives and dominates the local skyline. It was built in 1814 for Henry Dobell, who went bankrupt five years later. Then the mill was run by a union of creditors until 1832. The Russell family ran it for the next 128 years, when it was sold to Kent County Council, who have restored it. The mill is kept in working order to this day. It stands ¼ mile (400 m) southeast of the church.
