From 1790 to 1800, Philadelphia served as the temporary capital of the U.S. During that time, the U.S. Congress met in Congress Hall. The House of Representatives met on the first floor while the Senate convened upstairs. Presidents George Washington (second term) and John Adams both took the oath of office in this building.
In 1776, the Second Continental Congress signed the Declaration of Independence here. Eleven years later, in the same room, delegates to the Constitutional Convention created and signed an enduring framework of government - the United States Constitution. Although known today as Independence Hall, the building was constructed to be the Pennsylvania State House. It once housed all three branches of Pennsylvania’s colonial government.
