The Rockefeller Center venue opened on Dec. 27, 1932. But, maybe you've heard all of that before. Richard Claffey, senior vice president and general manager of Radio City, took amNewYork on an exclusive tour of the theater's secret places. Here are 10 of them.

Rockefeller Jr. sent his team on a cruise to Europe to look at the theaters abroad for inspiration. They were more impressed by the view on the ship, however, which led to the sunset-inspired, golden-arched ceiling, with red seats depicting the reflection of the sun on the ocean. This is the view of the "horizon" from the Presidents' Booth, the highest point in the audience, 165 feet from the stage.

While this one is kept out in a glass case for special visitors to browse, the others are tucked away in a drawer for safe-keeping.

Now, it's used as a quick and discreet way to shuttle celebrities between places without fanfare. Everyone from Ringo Starr to Jewel has walked its path.

As the organ players downstairs hit their notes, air travels from the organs through pipes in the ceiling and hits the sweet spots on the instruments above so that they are able to join in on the performance on their own.

Rothafel, a storied New York theater entrepreneur, is credited with transforming the silent film experience at movie palaces in the early 20th century. He hosted everyone from Judy Garland to Vincente Minnelli, and traces of his time there still remain, from the grand decor to the vintage book collection on the shelves.

There is no standard Rockette workout -- sorry, ladies -- but each dancer abides by her own routine. Credit: Nina Ruggiero The hall's organs block tiny doors Radio City's two Wurlitzer organs, sitting on either side of the stage, are the only two of their kind in the world. But in spite of the grand appearance of the instruments themselves, the hall's organ players have to crawl through a tiny door to get to their stools without being noticed.

Credit: Nina Ruggiero The venue keeps a uniform appearance While the Rockettes' costumes change many times in the course of just one show, every detail of the theater itself has remained the same since it opened in 1932. Given New York City historical landmark status in 1978 and national landmark status in 1987, Radio City Music Hall must keep everything in its original state -- down to the patterns of the wallpaper and carpets and the upholstery on the seats. When these are updated, Radio City actually deals with the same manufacturers it has used since it opened, some still run by the same families. Credit: Nina Ruggiero An artist's tennis elbow? Famed American muralist Ezra Winter created the enormous painting in Radio City Music Hall's lobby to depict mankind's search for the fountain of eternal youth, but was he inspired by his own aches and pains at the time? The mural, at 40 feet high and 60 feet wide, is so large, the entire piece had to be painted outdoors on a tennis court in sections and sewn together. Proud members of Winter's family still attend shows at Radio City today. Previous Secret Next Secret Comments Comments section is temporarily on hold. Here’s why.
