4The Stephen A. Schwarzman Building of the New York Public Library – New York

The 1911 Beaux-Arts flagship of the New York Public Library, designed by Carrère and Hastings, is one of the top tourist attractions in the city, not to mention one of the best research libraries in the city, too.

The standout hall is the Rose Main Reading Room, with 52-foot-high ceilings decorated with ornate murals and architectural detailing like gilt rosettes.
