Independence Visitor Center

Independence National Historical Park is a federally protected historic district in Philadelphia, Pennsylvania that preserves several sites associated with the American Revolution and the nation's founding history. Administered by the National Park Service, the 55-acre park comprises many of Philadelphia's most-visited historic sites within the Old City and Society Hill neighborhoods. The park has been nicknamed "America's most historic square mile" because of its abundance of historic landmarks.

The centerpiece of the park is Independence Hall, where the Declaration of Independence and the United States Constitution were debated and adopted by America's Founding Fathers in the late 18th century. Independence Hall was the principal meetinghouse of the Second Continental Congress from 1775 to 1783 and the Constitutional Convention in the summer of 1787.
