The Hook Windmill is one of eleven surviving 18th and early 19th century wind-powered gristmills on Long Island. The mill is one of three extant windmills built by Nathaniel Dominy V, a prominent East Hampton craftsman. The machinery of the Hook Mill is more complete than that of any other Long Island windmill.

Sitting in the center of North Main Street, the Hook Windmill built in 1806 was purchased by the Village of East Hampton in 1922. It became the first building to be preserved as a historic landmark and was added to the National Historic Register in 1978. 5D.
