Loyally guarded by 'Patience' and 'Fortitude' (the marble lions overlooking Fifth Ave), this beaux-arts show-off is one of NYC's best free attractions. When dedicated in 1911, New York’s flagship library ranked as the largest marble structure ever built in the US, and to this day, its Rose Main Reading Room steals the breath away with its lavish, coffered ceiling. While the room may be closed for restoration until early 2017, it's only one of several glories, among them the DeWitt Wallace Periodical Room.
This extraordinary building is home to precious manuscripts by just about every author of note in the English language, including an original copy of the Declaration of Independence and a Gutenberg Bible. The Map Division is equally astounding, with a collection that holds some 431,000 maps, 16,000 atlases and books on cartography, dating from the 16th century to the present.
