An official Path Through History Site! John D. Rockefeller, Jr. first opened the Observation Deck in 1933 to give something back to New Yorkers and their guests from around the world. The original design was inspired by the decks of the great ocean liners of the era-complete with deck chairs, gooseneck fixtures and vents inspired by a ship’s stacks. A trip here is like setting sail in the heart of the world's most dynamic city. Year round, visitors tour the plaza, Radio City Music Hall and the studios of NBC, as well as take in the spectacular 360-degree views from the Top of the Rock Observation Deck.
