A 690-acre private estate, designed by Frederick Law Olmsted in 1887 and given to the Long Island (New York) Park Commission in 1952. Although the site suffered severe damage from Hurricane Gloria in 1985, the pinetum features many specimens that date back to the original plantings. The arboretum has the most extensive collections of firs, spruces, pines, hemlocks, cypress, and yews on Long Island.
