During the Revolutionary War, France became a close friend of Americans seeking freedom from Great Britain. To honor its friendship with America, France gave the U.S. a special gift: sculptor Frederic-Auguste Bartholdi’s beautiful statue called Liberty Enlightening the World.

The Statue of Liberty arrived in New York Harbor on June 19, 1885. It came in 350 pieces packed into 214 crates. The statue was assembled on a pedestal base built by the United States. The 151-foot tall statue has become a worldwide symbol of freedom and democracy.

The Statue of Liberty’s home is Bedloe’s Island (renamed Liberty Island in 1956). From 1892 to 1943, “Lady Liberty” greeted over 12 million immigrants as they arrived on boats at the nearby Ellis Island Immigration Station.

The pedestal of the statue features words from poet Emma Lazarus that reflect immigrants’ hopes and dreams for freedom in America:

Give me your tired, your poor,
Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore.
Send these, the homeless, tempest-tost to me.

The statue represents Libertas, the Roman goddess of freedom. She holds a torch in one hand and a tablet inscribed with the date of the Declaration of Independence in the other.

Built in France, the statue is made of hundreds of thin copper sheets assembled on a frame of steel supports. The inner framework was engineered and designed by Gustave Eiffel. He later used the same design on the Eiffel Tower in Paris.

Eiffel’s design allows the Statue of Liberty to move with changes in temperature and wind speed. It also allowed staircases to be built on the inside of the statue. Visitors can climb to an observation deck inside the crown.

The outer layer of the statue is copper that’s only 3/32 of an inch thick — the thickness of two pennies put together. Despite how thin it is, the copper is strong. The amount of copper in the Statue of Liberty could make 30 million pennies!

When the statue was originally assembled, it was a dull brown color, reflecting the natural color of its copper plates. Over the next 30 years, though, it slowly turned to the green color you see today.

What happened? Was it magic? Nope! It was science. A natural weathering process — called oxidation — took place when air and water reacted with the copper plates.

Over time, the weathering of the copper created a thin layer of copper carbonate called a patina. Although some people were worried that the changing color of the statue meant it was decaying, the patina actually protects the copper underneath from further corrosion.

Here are a few interesting facts about “Lady Liberty” you might not have known:

  • The statue alone stands 151 feet tall.
  • The pedestal stands 154 feet tall, making the top of the torch 305 feet above ground level.
  • The statue contains 62,000 pounds of copper and 250,000 pounds of steel. The concrete pedestal weighs 54 million pounds.
  • Winds of 50 miles per hour can cause the statue to sway up to 3 inches and the torch up to 6 inches.
  • The 7 points of the crown represent the seven seas and the seven continents.

  1. 1. I think it is green because the colour green is a famous colour.

    2. I think it is green because the people that made it wanted to make it green because they liked the colour green.

    By Atalia

    • Hi, Atalia! Did you know that Lady Liberty wasn’t always green? She is made of copper that used to be a dull brown color. Over time, a natural weathering process called “oxidation” occurred, turning the brown copper green.

      We think she’s a beautiful sight standing there in all her glorious green wonder! Thanks so much for commenting today! :-)

  2. i know why the statue of liberty is green is becuse at first she was copper but then the weathering came and it turned the brown copper into green copper

    • Sure, Lauren, ask away! We’ll do our best to answer your question…that’s what Wonder Friends are for! :-)

    • You can surely write your own full-length Wonder and make/submit a video if you want to (we think that would be AWESOME, by the way), but you can also just let us know the idea of what you’re wondering about in a few short words! We bet there are other Wonder Friends who are wondering about the same things you are, Lauren! Thank you so much for this comment! :-)

  3. Great site with tons of good material. Be sure, I’ll use it in my English classes. The information is interesting and clear.
    You’re choosing the questions in a “catching way”…Thanks for your marvelous job

    • Hi, Susan! Thanks so much for your great comment! We love to meet new Wonder Friends and look forward to hearing how you engage your students with Wonder! :-)

  4. Isn’t it true that she was in a big junkyard before being built? My teacher showed a video, “America the Story of Us”, last week.

    • Hi, Serena! There are so many interesting facts about the Statue of Liberty, aren’t there? We haven’t heard about the junkyard fact, but we will definitely check out the video your teacher showed you so we can learn some new things, too! :-)

    • Thanks for telling us you think Wonderopolis is the best, Alexia! We really appreciate your kind words and are SUPER proud of you for your great grade in English! Keep up the good work, Wonder Friend! :-)

    • Nice work, Wonder Friend Pancake! We think you’re on the right track– the oxygen atoms and the water reacted with the copper, creating a process called oxidation, which turned the statue the green color we now recognize! Thanks for WONDERing with us today! :)

    • That’s great, Nicole G! We are very proud of all the WONDERing you’ve been doing about the Statue of Liberty! Thanks for reading all about Lady Liberty– and we hope to see you soon! :)

  5. I didn’t know that the green is not paint! Will the green stay there forever? Thank you for today’s wonder!! :) 😉

    • Hi Berkleigh, we’re so glad to hear that you learned something new with us today! What fun! The Statue of Liberty will be green for years and years to come, the statue is protected by the patina formed. We Wonder if you have seen the Statue of Liberty, Berkleigh? We hope you can visit New York in the future to see it up close! :)

  6. Sorry it’s late. 😉 Right now I’m in Clarkston, Michigan. I’m staying until Monday. But, bad news. For the rest two days we’re supposed to have thunderstorms. :( :( :( :( :( Can you have your wonder friends pray so it won’t storm for the next two days? ;(

    I think tomorrow’s wonder is that How can a deep breath calm you down when you get angry?

    Your wonder friend TJ :)

    • Hi TJ, thanks for sharing your comment. We hope you’re having a great time in Michigan with your friends and family this weekend. What kinds of fun games are you playing to keep you busy during these thunderstorms? We will see you soon, Wonder Friend! :)

    • Hey there Henry, we’re so glad that you have been WONDERing about the Statue of Liberty with us today! Such fun! The Statue of Liberty’s torch is a symbol of enlightenment. It represents that “Liberty Enlightens the World” — it’s a symbol of our freedom! :)

    • Hey Madi! Thanks for WONDERing with us today! We hope you can visit the Big Apple one day, and maybe you’ll see the Statue of Liberty, too! We bet you can find the answer to your question in this Wonder! :)

  7. I am a kindergarten teacher, and I can’t wait to explore your website with my five year olds! We will be studying American Symbols soon and I have included this wonder as well as the Washington Monument and the Bald Eagle into our lessons!

  8. I really enjoyed reading about the Statue of Liberty, but I have a question. Why is the Statue of Liberty a woman? How come it couldn’t have been a man or a child? By the way, this website is great! My teacher just started using it in class for many things and everyone fell in love with the creativity!!!

    • Hi Tiersa! The Statue of Liberty was actually a gift representing freedom to the United States! Thanks for WONDERing with us! :)

  9. I think that the statue of Liberty is a sign of independence and freedom. Also this is a really good passage for every-one to read.
