The 1787 Constitutional Convention met in Independence Hall in Philadelphia, Pennsylvania. Delegates gathered there to revise the Articles of Confederation but ultimately drafted an entirely new Constitution.
The building was then known as the Pennsylvania State House. It had already hosted the Second Continental Congress and the drafting and adoption of the Declaration of Independence, giving it an unusually central role in the nation's founding history.
The Constitutional Convention met from May 25 to September 17, 1787. George Washington presided, and delegates debated representation, executive power, federalism, taxation, and the relationship between the national government and the states.
The name Independence Hall became common later and reflects the building's association with independence. It is important not to confuse the convention's meeting place with Federal Hall in New York City, where the first United States Congress met under the Constitution in 1789.
