"The main branch of the New York Public Library is one of the country’s grandest Beaux Arts buildings, a temple to learning on Fifth Avenue between 40th and 42nd streets. At the end of the 19th century, John Bigelow, who oversaw the Tilden Trust, decided that as New York was becoming a global financial capital, it required a grand public library. When the Astor and Lenox libraries faced financial difficulties, he convinced them to merge and, with the Tilden Trust, underwrite the library that now stands next to Bryant Park. The firm of Carrère and Hastings was entrusted with the design, and construction began in 1902 on the building that would be the largest marble structure built up to that time in the United States. The elegant main reading room with its soaring carved-wood ceilings is the highlight of its interiors. The library hosts temporary exhibitions related to literary and cultural topics that draw on its extensive collection of books and other printed materials. The two beloved lions in Tennessee marble—Patience and Fortitude—have stood at the entrance to the library since it opened in 1911 and were created by sculptor Edward Clark Potter."
