Independence National Historical Park

Philadelphia

Independence National Historical Park is a federally protected historic district in Philadelphia, Pennsylvania, United States 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, a UNESCO World Heritage Site, where the Declaration of Independence and the United States Constitution were debated and adopted 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. Across the street from Independence Hall, the Liberty Bell, an iconic symbol of American independence, is displayed in the Liberty Bell Center.
