Formerly the Philadelphia County Courthouse, Congress Hall was the meeting place of the U.S. Congress from 1790 to 1800—one of the most important decades in our nation's history. Here the Bill of Rights was added to the Constitution; Alexander Hamilton's proposals for a mint and a national bank were enacted; and Vermont, Kentucky, and Tennessee became the first new states after the original colonies. On the first floor you can find the House of Representatives, where President John Adams was inaugurated in 1797. On the second floor is the Senate chamber, where in 1793 George Washington was inaugurated for his second term. Both chambers have been authentically restored.
