Carnegie Hill is a neighborhood within the Upper East Side, in the borough of Manhattan in New York City. Its boundaries are 86th Street on the south, Fifth Avenue (Central Park) on the west, with a northern boundary at 98th Street that continues just past Park Avenue and turns south to 96th Street and proceeds east up to, but not including, Third Avenue. The neighborhood is part of Manhattan Community District 8. In the 2000s, the perceived northern boundary on Park Avenue has edged over 96th Street into what was traditionally Spanish Harlem, leading to that area sometimes being called Upper Carnegie Hill, especially by real-estate brokers. According to the official Carnegie Hill Neighbors website, the Carnegie Hill neighborhood extends from 86th to 98th Streets, from Fifth Avenue up to, but not including, Third Avenue. History The neighborhood is named after the mansion that Andrew Carnegie built at Fifth Avenue and 91st Street in 1901. Today the mansion houses the Cooper Hewitt, Smithsonian Design Museum, a branch of the Smithsonian Institution. Facing it on 91st Street is the Otto H. Kahn House, a Florentine palazzo, now housing the Convent of the Sacred Heart. A number of other townhouses in the area have been converted to schools, including the recent purchase of the William Goadby and Florence Baker Loew House on 93rd Street by the Spence School. The Lycée Français, housed in the former Virginia Graham Fair Vanderbilt House, held an additional townhouse space on 93rd between Fifth and Madison Avenue until 2005, when the property was sold to a private owner. The architecture of the neighborhood includes apartment buildings along Park Avenue and Fifth Avenue, brownstones (with stoops) and townhouses on the side streets, condos, co-ops and a handful of mansions, of which some are now used by the Cooper Hewitt, Smithsonian Design Museum, The Jewish Museum, the National Academy of Design, the Dalton School and other organizations. From the 1950s to 1971, the National Audubon Society was housed in the Willard Straight House, a red brick Colonial Revival townhouse at 1130 Fifth Avenue. When it moved to NoHo, the International Center of Photography moved in but later consolidated its operations in Midtown near Bryant Park. In 2001, it again became a private residence. In 1989, the Jewish Museum demolished its 1963 modernist addition and courtyard, replacing it with a new extension opened in 1993 that mimics the French Gothic
