Bryant Park is a 9.603 acre (39,000 m²) privately managed public park located in the New York City borough of Manhattan. It is located between Fifth and Sixth Avenues and between 40th and 42nd Streets in Midtown Manhattan. Although technically the main building of the New York Public Library is located within the park, effectively it forms the park's functional eastern boundary, making Sixth Avenue the park's primary entrance. Although part of the New York City Department of Parks and Recreation, Bryant Park is managed by a private not-for-profit corporation, the Bryant Park Corporation. The park is cited as a model for the success of public-private partnerships.
Bryant Park is built entirely over an underground structure which houses the New York Public Library's archives. In the 1980s, the park was closed to the public and excavated. The new library facilities were built below ground level and the park was restored above it.
