Rayleigh Windmill is a grade II listed Tower mill at Rayleigh, Essex, England which has been restored as a landmark and is used as a museum.
Rayleigh Windmill was built in 1809 for Thomas Higgs, a timber merchant of Rayleigh. Higgs was bankrupt in 1815 and the mill was sold to William Hart of Woodham Mortimer in 1817. Hart sold the mill to George Britton in 1845 and the mill passed to his sons John and Samuel in 1869. ?150 was spent putting the mill into repair. The Britton brothers left Rayleigh in 1884 and were bankrupt in 1886. Thomas James Brown was the next miller, and the last to work the mill by wind c1907. The cap and sails were removed c1909 and the mill was worked by a steam engine then an oil engine and latterly by electric motor until at least 1937.
The mill was taken over for use as a museum by Rayleigh and District Antiquarian and Natural History Society, formally opening on 16 May 1970. The capless mill stood for many years with a crenellated top but in 1972 Rayleigh Urban District Council launched an appeal to restore the mill as a landmark. By the autumn of 1974 a new cap and sails had been made and fitted by millwrights John Lawn and Philip Barrett-Lennard.
In 2005, restoration work costing ?340,000 was funded by the Thames Gateway South Essex Partnership.
