7 Odd Facts About Lady Liberty

The crown of the Statue of Liberty will be open for business again July 4, the first time since 9/11. NPR collected a few facts about Lady Liberty you might not know:

• The 7 spikes: Liberty's crown does not symbolize the 7 continents or seas, as even the National Parks Service reports. They're sun rays, and the circle is a "nimbus."
• She's so heavy: The statute is made of 31 tons of copper, 125 tons of steel, and the base consists of a whopping 27,000 tons of concrete.

• No fire, please: The torch has been off limits since World War I, when German saboteurs set off an explosion nearby that sent shrapnel into it and the statue's skirt.
• She dances: In high winds, the Lady sways 3 inches; the torch can move up to 5 inches.
• Suicide: Three people have taken their own lives in plunges from the statue, the first in—you got it—1929.
• Movie star: Aside from acting as Columbia's mascot, the statue has figured prominently in films from Charlie Chaplin and Alfred Hitchcock.
• Vandal magnet: The crown has attracted all manner of used chewing gum and lipstick graffiti.
