New York Public Library

Patience and Fortitude, the two majestic marble lions standing guard at the entrance to the New York Public Library on Fifth Avenue, are the guardians of one of the city's best free attractions. Completed in 1911, the library was considered the largest marble structure ever built in the United States, and its recently restored Rose Main Reading Room is breathtaking with its lavish coffered ceiling. Not just a showpiece, the library is open to the public, earning it the title of the world's most glamorous coworking space.
