Independence Hall in Philadelphia, PA.
Independence Hall is the building where both the United States Declaration of Independence and the United States Constitution were debated and adopted. It is now the centerpiece of the Independence National Historical Park in Philadelphia, Pennsylvania.
The building was completed in 1753 as the Pennsylvania State House, and served as the capitol for the Province and Commonwealth of Pennsylvania until the state capital moved to Lancaster in 1799. It became the principal meeting place of the Second Continental Congress from 1775 to 1783 and was the site of the Constitutional Convention in the summer of 1787.
