200 Madison Avenue (also known as the Marshall Field Building, Astor Estate Building, International Combustion Building, and Tower Building) is a 25-story office building in the Murray Hill neighborhood of Manhattan in New York City. It is along the west side of Madison Avenue between 35th and 36th Streets. Designed by Warren and Wetmore, it was built from 1925 to 1926. 200 Madison Avenue's facade is largely made of red brick with limestone trim, as well as window spandrels made of terracotta and cast iron. The ground story is made of limestone and contains entrances from Madison Avenue, 35th Street, and 36th Street. The building contains a setback above its ninth story. The "T"-shaped lobby is designed in a neo-Renaissance style, with a north–south arcade connecting 35th and 36th Streets, as well as an elevator lobby extending toward Madison Avenue. The lobby's ornate interior contains gilded decorations and various animal motifs. Due to zoning restrictions on the eastern part of the site, the lower stories originally served as an apartment hotel, while the smaller upper stories contained offices. Since the 1910s, the Astor family had wanted to develop a commercial building on the site, but the plans were delayed for a decade due to opposition from J. P. Morgan Jr. and other local residents. 200 Madison Avenue was developed by a syndicate that included Texas entrepreneur Jesse H. Jones. The building was originally known for its largest tenants, Marshall Field and Company and International Combustion. The apartment hotel initially occupied the second through ninth floors, but it was unprofitable, closed in 1939, and was turned into office space, with tenants such as Amtorg Trading Corporation. The building was sold several times in the 20th century, including to a group representing Philippine president Ferdinand Marcos during the 1980s. George V. Comfort and the Loeb Realty and Development Corporation acquired 200 Madison Avenue in the 1990s, and the New York City Landmarks Preservation Commission designated the building's lobby as an official landmark in 2021.
