In 1866, a club was formed and chartered under the name of "The South Side Sportsmen's Club of Long Island". The first article of the constitution of the association stated, "This club is established for the protection of game birds and fish and for the promotion of social intercourse among its members."
The club's facilities included a main clubhouse building, a smaller residence building, and an old wheat and corn-grinding gristmill built c.1750 among other service buildings. Part of the main building built in 1820 was originally Snedecor's Tavern (known as "Obe Snedecor's") owned by Eliphalet (Liff) Snedecor on the old stage road.
The "shingle style" clubhouse was the first building designed by architect Bradford Gilbert. Between 1866 and 1973, it was used as the clubhouse. Members and their guests used the residence when visiting for fishing, sporting clays and other types of outdoor recreation. The main clubhouse contains an elaborate library, billiard room, dining hall, clubhouse room, and various bedrooms.
The South Side Sportsmen's Club promoted many of the laws protecting game not only on Long Island but throughout the state. The club is no longer in existence, and the property is now part of the Connetquot River State Park Preserve owned by the New York State Office of Parks, Recreation and Historic Preservation.
South Side Sportsmen's Club was added to the National Register of Historic Places in 1973.
