At 23 feet 3/4 inches, the sails of this mill are the smallest of any found on a Long Island windmill.

The Southampton Colony Chapter of the Daughters of the Revolution placed a plaque above the door in 1934 when it was designated a part of a public park.

Originally the windmill was built in Sag Harbor and moved by oxen to the commons in Water Mill.

The Watermill Green surrounding the Windmill is used for community activities such as antique auto shows and events throughout the year.

By 1890, wealthy city dwellers were buying properties in the east end and creating large country estates, some farmers turned to the service economy of being tradesmen to these newcomers.

They had purchased eight acres southwest of the windmill and built a large Queen Anne style summer house on the site.

The mill now served as a decoration on the Keyes estate, over time the stones under it were replaced by a foundation and ivy grew on the walls.

In 1909, Edward P. Morse, a Brooklyn shipbuilder, bought the Keyes property, including the triangle the windmill sat on.

The hurricane of 1938 did considerable damage to the mill and additional repairs were made, the cap was dislodged and the tailpole needed re-attachment.
