West Blatchington Windmill was built circa 1820 on a tall flint and brick tower to which abutted barns on the north, south and west side. It was beautifully illustrated by John Constable in a watercolour dated 5th November 1825.

The design is of the style known as a 'Smock' mill due to the resemblance in silhouette, to the garment worn by the millers and shepherds of that period. Normally eight sided, the mill here is only six sided and, along with many other features, is unique in the milling world.
