48th Street (Manhattan) in the context of "United Nations headquarters"

Rockefeller Center is a complex of 19 commercial buildings covering 22 acres (8.9 ha) between 48th Street and 51st Street in the Midtown Manhattan neighborhood of New York City. The 14 original Art Deco buildings, commissioned by the Rockefeller family, span the area between Fifth Avenue and Sixth Avenue, split by a large sunken square and a private street called Rockefeller Plaza. Later additions include 75 Rockefeller Plaza across 51st Street at the north end of Rockefeller Plaza, and four International Style buildings on the west side of Sixth Avenue.

In 1928, Columbia University, the owner of the site, leased the land to John D. Rockefeller Jr., the complex's developer. Originally envisioned as the site for a new Metropolitan Opera building, the current Rockefeller Center came about after the Met could not afford to move to the proposed new building. Various plans were discussed before the current one was approved in 1932. Construction of Rockefeller Center started in 1931, and the first buildings opened in 1933. The core of the complex was completed by 1939. Described as one of the greatest projects of the Great Depression era, Rockefeller Center became a New York City designated landmark in 1985 and a National Historic Landmark in 1987. The complex and associated land has been controlled since 2000 by Tishman Speyer, which bought the property for $1.85 billion.

The James Earl Jones Theatre, originally the Cort Theatre, is a Broadway theater at 138 West 48th Street, between Seventh Avenue and Sixth Avenue, in the Theater District of Midtown Manhattan in New York City, New York, U.S. It was built in 1912 and designed by architect Thomas W. Lamb for impresario John Cort. An annex west of the original theater, built between 2021 and 2022, was designed by Kostow Greenwood Architects. The Jones has 1,092 seats across three levels and is operated by the Shubert Organization. Both the facade and interior of the theater are New York City designated landmarks.

The theater maintains much of its original neoclassical design. Its 48th Street facade has a glass-and-metal marquee shielding the entrances, as well as a colonnade with an additional story above. The lobby has marble paneling and a coved ceiling. The auditorium contains a ground-level orchestra and two overhanging balconies with boxes. The auditorium's proscenium arch is designed with "art glass" that can illuminate during performances, and its ceiling is coved. The western annex contains lounges, restrooms, and backstage areas.
