Some of the most important documents in American history were composed and debated within the Pennsylvania State House, now known as Independence Hall. In 1776, the Second Continental Congress voted to approve the Declaration of Independence, which said that the American colonies would no longer be subject to the British rule. In 1787, Independence Hall hosted discussions for a new Constitution, which even today remains the foundation of government for the United States. The Liberty Bell, which once hung in the steeple of Independence Hall, has also become an important American symbol. Today, millions of people visit Independence Hall each year to celebrate the origins of America.
