Where did the 1787 Constitutional Convention meet while drafting the United States Constitution?

The 1787 Constitutional Convention met at Independence Hall in Philadelphia while drafting the United States Constitution.

The building was then known as the Pennsylvania State House. Delegates from twelve states assembled there from May 25 to September 17, 1787, to revise the Articles of Confederation. Instead, they produced an entirely new framework for the federal government.

The same building had already hosted the Second Continental Congress and the Constitutional Congress. The Declaration of Independence was adopted there in 1776, giving the site an unusually important place in the country’s founding history.

The convention’s meetings were conducted in private, and George Washington presided. Delegates debated representation, federal powers, slavery, executive authority, and the relationship between states and the national government. The Constitution was signed in the building’s Assembly Room on September 17, 1787. Federal Hall in New York City was important to the early federal government, but it was not the convention’s meeting place.
