Founded in 1886, the mission of The Suffolk County Historical Society is to collect, preserve and interpret the ongoing history of Suffolk County, NY and its people.
In 1994 the United States Department of the Interior listed the society’s building on the National Register of Historic Places.
Today, over 20,000 historical artifacts are cared for in the museum. Permanent and changing exhibitions are used to interpret important themes in Suffolk County history. The artifact collections are broad in nature and are particularly strong in the areas of General History, Decorative Arts, Fine and Folk Arts, Costumes and Textiles, and Ethnographic and Natural History artifacts.
