A mill has stood on this site at the head of Stony Brook Harbor since around 1700, when the original structure was built to serve the agricultural community of colonial Long Island. A severe storm destroyed that first mill around 1750, and the current building — constructed on the same location — dates from the same period of replacement.
The mill operated commercially for generations, grinding grain for the local farming community. By the twentieth century it had become a heritage site rather than a working commercial operation. The Ward Melville Heritage Organization now maintains it and operates guided tours on Sunday afternoons from April through October, staffed by millers and guides who demonstrate the machinery and explain the mill's history. The Country Store adjacent to the mill is open during tour hours.
The setting — a working water mill with a pond at the edge of a colonial village — draws visitors as much for its architectural and mechanical integrity as for its haunted reputation. At $4 admission for adults (cash only), it is among the more affordable historic attractions on Long Island.
Sources
The ghost associated with the Stony Brook Grist Mill is described consistently in the accounts that circulate about the site: a blonde woman wearing a white dress, seen in or near the mill building. The figure appears without evident purpose — not reenacting a specific event, not interacting with visitors in a documented way — and the accounts don't attach her to a named individual or a specific historical incident at the mill.
Paranormal tours in the Stony Brook area include the Grist Mill as a stop, and the figure is mentioned in at least one Long Island haunted places guide, but the mill's official tour programming does not foreground the haunted lore. The Sunday miller tours focus on the mechanical history and agricultural context of the site.
The absence of a named figure or anchoring story makes this a thinner paranormal tradition than some Long Island sites. The attraction is primarily the mill itself.
Notable Entities
A guided tour of the working 1750 grist mill led by a miller or tour guide demonstrating how the machinery operates. The Country Store is open during tour hours. The mill occupies the site of an original c.1700 mill destroyed in a storm; the woman in white is associated with the replacement structure.

Historic Huguenot Street preserves one of the oldest intact early-American streets in North America. The Huguenot Patentees — French Protestants who fled persecution following the 1685 revocation of the Edict of Nantes — settled here in the 1670s and built the surviving stone houses in the early 18th century. The district was declared a National Historic Landmark in 1965.

Frederick Philipse I received a royal charter for 52,000 acres of Hudson Valley land in 1693. He and his descendants operated the manor as a commercial enterprise for generations, shipping goods from a wharf on the Pocantico River and milling grain for export to the Caribbean. At the heart of the operation was enslaved African labor: Adolphus Philipse's 1750 probate inventory listed 23 enslaved men, women, and children as the estate's most valuable property. Historic Hudson Valley has operated the site since the 1940s with a mission centered on the stories of those workers.

The Seward House was built circa 1816 by Judge Elijah Miller and became the lifelong home of William H. Seward — U.S. senator, two-term governor of New York, and Secretary of State under Lincoln and Andrew Johnson. Declared a National Historic Landmark in 1964, it preserves the night of April 14, 1865, when Lewis Powell entered the house and attacked Seward with a Bowie knife while Lincoln was being shot at Ford's Theatre.
