• There are 1,575 steps from the lobby to the 86th floor.
• Constructed with 60,000 tons of structural steel.
• As a popular symbol of the city and its spirit, the building has been featured on countless artistic impressions of the city; for instance, the building has been featured on album covers of music of nearly every genre, from jazz of the thirties to hip hop of the '00s.
• Soon after opening it became a major tourist attraction, attracting many famous people, including the French Prime Minister, Albert Einstein, Winston Churchill, Pope Pius XII, Fidel Castro and Queen Elisabeth II, to name a few.
