They call her Lady Liberty and inscribed on her base is a sonnet by Emma Lazarus:

The New Colossus

Not like the brazen giant of Greek fame,
With conquering limbs astride from land to land;
Here at our sea-washed, sunset gates shall stand
A mighty woman with a torch, whose flame
Is the imprisoned lightning, and her name
Mother of Exiles. From her beacon-hand
Glows world-wide welcome; her mild eyes command
The air-bridged harbor that twin cities frame.
“Keep, ancient lands, your storied pomp!” cries she
With silent lips. “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,
I lift my lamp beside the golden door!”

The Statue of Liberty

Here is some history of the Statue of Liberty:

Located on Liberty Island in New York Harbor, the Statue of Liberty was a gift from the people of France to the people of the United States and is one of the most universal symbols of freedom in the world. The Statue of Liberty was dedicated on October 28, 1886 and was designated a National Monument on October 15, 1924. The Statue was extensively restored in time for her one-hundred year anniversary on July 4, 1986. The Statue of Liberty is the most visited tourist attraction in New York City.  It is also the 2nd most photographed landmark in the United States behind the Golden Gate Bridge in San Francisco.
