The museum complex is comprised of nine acres with three modern exhibition buildings and five historic structures. The Art Museum houses a permanent collection of American art and two changing exhibition galleries. The 40,000-square-foot Carriage Museum is home to the finest collection of American horse-drawn transportation artifacts in the world
The Decoy gallery replicates authentic Long Island wetlands as a “natural habitat” for the display of shorebirds and duck decoys. An early 20th-century bayman’s shack, complete with tools, furnishings and decoys in various stages of completion illustrates the process and methods used by carvers.
