5. The Upper East Side contains some of the most architecturally fascinating diplomatic missions
The Upper East Side houses over 20 diplomatic missions, many of which are located in former mansions. The Consulate-General of Greece in New York, for instance, is in the former 79th Street residence of George L. Rives, who served as U.S. Assistant Secretary of State. Others located in former mansions, many of which are between Fifth Avenue and Madison Avenue, include the Consulates-General of Russia, India, Indonesia, France, and Austria.
Additionally, there are about a dozen missions to the UN located in historic homes within historic districts, including the Upper East Side Historic District and the Carnegie Hill Historic District. Countries include Belarus, Mongolia, Ivory Coast, Mali, and Iraq.
