The Pultneyville Historical Society (PHS), a not-for-profit organization, was founded in 1964. It was chartered in 1971 by the New York State Board of Regents to acquire, preserve and present the history of the Township of Williamson.

Purchased in 1996, the Society's c.1858 landmark home was the former Auchampaugh residence. With a harbor view, it is located at 4130 Mill Street in Pultneyville, New York. Along the Seaway Trail, Pultneyville is a hamlet located in the Town of Williamson which is situated on the southern shore of Lake Ontario in Wayne County. The home provides meeting and office space for PHS, houses the society's extensive archival and artifacts collection, space for permanent and traveling exhibits and a gift shop.  It is open to the public on weekends throughout the summer months and by special appointment.

PHS also holds the deeds of nearby Centennial Park in the heart of Pultneyville and Gates Hall, a New York State and National Landmark listed on both the New York State Register and the National Register of Historic Places. Gates Hall is a cultural highlight of the area and bears distinction as the second oldest active little theatre in the United States. The Society remains committed to preserving both properties for community activities and use.
