"Rockefeller Center was one of the great construction projects of the Great Depression, a complex of 14 buildings between Fifth and Sixth avenues and 48th and 51st streets built over the 1930s. It's also one of America's grandest examples of Art Deco design, from the Indiana-limestone-clad buildings themselves to its interior murals and allegorical figures in panels above the entries to the various buildings. (Daniel Okrent recounts the fascinating history of the complex in detail in his acclaimed Great Fortune: The Epic of Rockefeller Center .) For many travelers to New York, the center is a favorite destination even if they aren't students of architecture or urban planning. It's the home of Radio City Music Hall, where the Rockettes perform; its 70th-floor observation deck offers sweeping views of the city; and every morning tourists gather outside the windows of the NBC studios during the broadcast of The Today Show. The center also hosts temporary large-scale art installations, like Jeff Koons's enormous dancer and flower puppy in recent years, and the lighting of its Christmas tree marks the unofficial start of the holiday season. Another bucket-list experience here is taking a turn on the small sunken ice rink under the golden statue of Prometheus. Just across Fifth Avenue from Rockefeller Center is another New York landmark, St. Patrick's Cathedral, looking better than ever after a multiyear renovation that included a thorough cleaning of the Gothic building's facade."
