Old Westbury, NY

Old Westbury is a North Shore Long Island village split between the towns of North Hempstead and Oyster Bay in Nassau County. It is small in population but famous for estate-scale wealth, with families such as the Whitneys and Vanderbilts tied to its history. Gertrude Vanderbilt Whitney, founder of the Whitney Museum, lived at Apple Green, and the Meadow Brook Polo Club is one of the village's defining landmarks. Old Westbury feels less suburban than aristocratic, with large properties and deep Gold Coast history.
