The United States Constitution was signed in Independence Hall in 1787, a site connected with America250.
The building stood in Philadelphia and was then called the Pennsylvania State House. The Constitutional Convention met there from May through September 1787. Delegates debated representation, executive power, federal authority, taxation, and the relationship between the states and the national government.
The Constitution was signed in the building on September 17, 1787. The same structure had hosted the Second Continental Congress and the signing of the Declaration of Independence in 1776, making it one of the most important surviving places associated with the United States' founding era.
The name Independence Hall became common later, reflecting the building's association with independence and the Declaration. It should not be confused with Federal Hall in New York City, where the First Congress met and George Washington was inaugurated in 1789. Independence Hall is now part of Independence National Historical Park.
