Ritz Tower, Luxury apartment building in Midtown East, Manhattan, US.

The Ritz Tower is a 41-story apartment hotel at 465 Park Avenue, designed by Emery Roth and Thomas Hastings and completed in 1926. It rises 541 feet (165 m) to its pinnacle, with setbacks on the 4th, 19th, 21st, 25th, and 33rd floors, a pyramidal roof, and an obelisk. The lower three floors are rusticated limestone; upper floors are tan brick with Italian Renaissance terracotta ornament.

Built from 1925 to 1926 for journalist Arthur Brisbane, the Ritz Tower was designed by Emery Roth with Thomas Hastings of Carrère and Hastings. Classified as an apartment hotel, it rose about 541 feet with 41 stories, then the tallest residential building in the city. Brisbane hired the Ritz-Carlton Company to run it, sold it to William Randolph Hearst in 1929, and Hearst gave it up to bondholders in 1938; it became a housing cooperative in 1956 and a city landmark in 2002.

The name came from the Ritz-Carlton Company, which Arthur Brisbane hired to run the building and its restaurants after it opened on October 15, 1926. Its ground-floor retail space later housed Le Pavillon, one of the first authentic French restaurants in the United States. Residents have included many figures from the media world.

The building is a private residence, so viewing is from the street. The ornament is concentrated at the base, the setbacks and the top, while the middle floors are comparatively bare; the three-story rusticated limestone base and the sculpted putti and urns are best seen from the Park Avenue and East 57th Street sidewalks. The pyramidal roof and obelisk read from a distance along Park Avenue.

The corner lot at Park Avenue and 57th Street was never bought by Arthur Brisbane; the Roome family's brownstone stood there and they leased the land for $15,000 a year. Had they reclaimed it, the fourth-floor setback section could have been detached and fitted with its own staircase and elevator.
