Le Corbusier's landmark UN Headquarters is located on the East River. The masterpiece art deco towers of Rockefeller Center and adjoining Radio City sit opposite 5th Avenue from St. Patrick's Cathedral, the seat of the city's archdiocese. Fifth Avenue below 59th remains the toniest and most exclusive retail neighborhood in New York City, home to names like Saks, Tiffany, FAO Schwarz and Bendel. Murray Hill north of 34th Street is home to some of the city's nicest brownstones. Much of the real estate in this neighborhood is likewise quite expensive, and the restaurants, bars and other facilities notably cater to a higher-paying clientele.
