The Long Island Museum of American Art, History, and Carriages allows visitors the chance to learn about three unique subjects. Through recreated period rooms and permanent and traveling exhibits, visitors can explore Long Island history and its relation to natural history; in the art galleries, they can view pieces from the early 1800s to the present day; and, in the 10 carriage galleries, they can compare almost 100 carriages. Visitors may also walk through the grounds and the historic structures on-site, dating from the late 18th through the late 19th century.

The museum offers exhibits and tours and educational programs for school groups.
