West Blatchington Windmill was built in the 1820s, first appearing on Greenwood's map of 1823. It was painted by John Constable in 1825. The mill is hexagonal in plan, whereas most smock mills are octagonal. It was working until 1897, when two sails were damaged. In 1937, the mill was acquired from the Marquess of Abergavenny by Hove Corporation, and has been maintained as a landmark.
