740 Park Avenue
740 Park Avenue is a luxury apartment building on Park Avenue in Manhattan, which has been the home to many wealthy and famous residents. The building also carries the address 71 East 71st Street.

An apartment previously belonging to John D. Rockefeller, Jr., currently owned by Stephen Schwarzman, when sold by Saul P. Steinberg in 2000, brought a price "slightly above or below $30 million," reportedly the highest price ever paid on Park Avenue. Rockefeller moved to the building in 1937. The apartment house has 31 units, and has the highest ceilings and widest hallways on Park Avenue. The exterior of the building is clad with limestone. It was built in 1929, designed by Rosario Candela and Arthur Loomis Harmon, the design partner of Shreve, Lamb and Harmon. The builder was James T. Lee, grandfather of Jacqueline Kennedy Onassis. Life in the building is amusingly described in the New York Social Diary. In 2005, author Michael Gross published a detailed book on the building and its history, 740 Park: The Story of the World's Richest Apartment Building. According to Gross, builder Lee's daughter Janet Lee Bouvier and son-in-law Jack Bouvier took the final open lease (according to one account, for free), and their daughter Jacqueline Kennedy Onassis grew up there.
