details of the Warburg Mansion, the museum's home since 1947. The limestone was crafted in Morningside Heights at the Cathedral Stoneworks. Frank Lloyd Wright's originally maligned and now celebrated Guggenheim Museum opened on Fifth Avenue in 1959. The New York Road Runners occupies a townhouse around the corner at 9 East 89th Street, a block informally known as Fred Lebow Place. Similar to the official lines of the historic district, the borders of the neighborhood form an irregular rectangle and the northern boundary, which traditionally was 96th Street, has on Park Avenue edged into what was traditionally Spanish Harlem. The northern section neighborhood was once seen as a less fashionable end of the East Side, but is now prized for its aesthetic sensibility, museums, schools, restaurants and neighborhood feel. Besides, Andrew Carnegie, Marjorie Merriweather Post, Margaret Rockefeller Strong and John Hay Whitney all made their homes north of 90th Street. Preservation The Carnegie Hill Historic District, designated as such by the Landmarks Preservation Commission on July 23, 1974, and then expanded on December 21, 1993, runs from 86th Street in the south to just north of 98th Street in the north. Its western boundary is Central Park, and its eastern boundary varies from Madison Avenue in some parts to Lexington Avenue farther east in others. There are efforts to expand this district in order to protect undesignated landmarks, including 179 East 93rd Street, where the Marx Brothers were raised. Proponents include the 93rd Street Beautification Association and Carnegie Hill Neighbors, organizations which, seeking to preserve the village-like environment, spurred the creation of the historic district and actively monitor its well being. In its more than thirty years of operation, its well-publicized battles have included advocating against an adult education center near the 92nd Street Y, plans for more high rise apartments and additions to existing brownstones. Education Hunter College High School, a highly selective nationally ranked high school, is located at the corner of 94th Street and Park Avenue. The New York City Department of Education operates public schools such as Lower Lab, one of three gifted and talented programs in NYC. The main campus of the La Scuola d'Italia Guglielmo Marconi Italian international school is in Carnegie Hill at 12 East 96th Street.
