New York Life Building

The New York Life Building is the headquarters of the New York Life Insurance Company at 51 Madison Avenue in the Rose Hill and NoMad neighborhoods of Manhattan in New York City. The building, designed by Cass Gilbert, abuts Madison Square Park and occupies an entire city block bounded by Madison Avenue, Park Avenue South, and 26th and 27th Streets.

The New York Life Building was designed with Gothic Revival details similar to Gilbert's previous commissions, including 90 West Street and the Woolworth Building. The tower is 615 feet (187 m) tall (the equivalent of forty stories), consisting of 34 office stories topped by a pyramidal, gilded six-story roof. At the time of the building's construction, many structures were being built in the Art Deco style, and so Gilbert's design incorporated Art Deco influences in its massing while retaining the older-style Gothic Revival detailing. The New York Life Building is distinguished from the skyline by its gilded roof.

The New York Life Building was constructed in 1927–1928 on the site of Madison Square Garden. Upon completion, the New York Life Building was described as being run "like a small city". After World War II, New York Life became especially profitable, and built an annex to the north between 1960 and 1962. Additionally, New York Life completed a series of renovations to the original building during the late 20th century. The building was added to the National Register of Historic Places as a National Historic Landmark in 1978 and was designated a city landmark by the New York City Landmarks Preservation Commission in 2000.
