Windmill at Water Mill, Montauk Highway & Halsey Lane, Water Mill, Suffolk County, NY

Significance: The Windmill at Water Mill is one of 11 extant late 18th and early 19th century wind-driven gristmills on eastern Long Island; it served the milling needs of local farmers when eastern Long Island was primarily a grain and cattle producing area lacking in sufficient water power. One of nine remaining windmills with major internals works, the mill structure and machinery offer important documentation of the wood joinery techniques used in 17th, 18th and 19th century American domestic and utilitarian architecture. The mill also helps document eastern Long Island's cultural and economic ties to New England, as well as the migration of millwriting technologies from England.
