It stands on a triangular one-acre village park bounded by Pantigo Road, North Main Street and the village cemetery. Originally a grist mill, it was operated by the Dominy family, who were clock and cabinetmakers and housewrights, until 1910. It is one of four surviving Long Island windmills built by the Dominys and one of three that remain on their original sites. Its boat-shaped cap is unique to windmills on Long Island. The mill is described as the best preserved of the island's windmills and as completely intact. Inside, the drive system includes a brake wheel, wallower, great spur wheel, and two sets of millstones, one French burr and one granite. Restored and operable, it is now kept by the Village of East Hampton as a museum of this rare regional technology. It was recorded by the Historic American Engineering Record in 1976.","period_of_significance":null,"architect_builder":"Builder: Nathaniel Dominy V","architectural_style":"Smock mill with boat-shaped cap","criteria":[],"status_note":"Restored, fully operable and in excellent condition; maintained by the Village of East Hampton as a museum.
