Mount Sinai Hospital, founded in 1852, is one of the oldest and largest teaching hospitals in the United States. Located on the eastern border of Central Park stretching along Fifth Avenue between 98th to 103rd Street in the New York City borough of Manhattan, Mount Sinai also has a number of hospital affiliates in the New York metropolitan area including Brooklyn Hospital Center, and an additional campus, the Mount Sinai Hospital of Queens. The hospital is also affiliated with the Icahn School of Medicine at Mount Sinai, which opened in September 1968. In 2013, The Mount Sinai Hospital joined with the Continuum Health Partners in the creation of The Mount Sinai Health System. The system encompasses the Icahn School of Medicine at Mount Sinai and seven hospital campuses in the New York metropolitan area, as well as a large, regional ambulatory footprint. In 2014 and 2015 two of the biggest hospitals in Manhattan that were part of the Health System were formally renamed with Mount Sinai moniker: St. Luke's Hospital was renamed Mount Sinai St. Luke's and Roosevelt Hospital was renamed Mount Sinai West.
