Carnegie Hill

In the 2000s, the perceived northern boundary on Park Avenue has edged over 96th Street into what was traditionally Spanish Harlem,[3] leading to that area sometimes being called Upper Carnegie Hill, especially by real-estate brokers.

Facing it across 91st Street is the Italian palazzo-style Otto H. Kahn House, currently the home of the Convent of the Sacred Heart, a Roman Catholic girls' school.

[14] Besides, Andrew Carnegie, Marjorie Merriweather Post, Margaret Rockefeller Strong and John Hay Whitney all made their homes north of 90th Street.

[16] Proponents include the 93rd Street Beautification Association[17] and Carnegie Hill Neighbors,[18] organizations which, seeking to preserve the village-like environment, spurred the creation of the historic district and actively monitor its well being.

[19] 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.

The Andrew Carnegie Mansion is a neighborhood landmark and its namesake structure.
