The New York Cancer Hospital (NYCH) on the Upper West Side of Manhattan, New York City was a cancer treatment and research institution founded in 1884. The building was located at 455 Central Park West between West 105th and 106th Streets, and built between 1884 and 1886 with additions made between 1889 and 1890; it was designed by Charles Coolidge Haight in the Late Gothic and French Chateau styles – inspired by the chateaux of the Loire Valley. It was the first hospital in the United States dedicated specifically for the treatment of cancer, and the second in the world after the London Cancer Hospital. After outgrowing the original building and moving, it became what is today known as Memorial Sloan-Kettering Cancer Center.
