The Second Continental Congress adopted the United States Declaration of Independence in Independence Hall.
The building stood in Philadelphia as the Pennsylvania State House when Congress met there in 1776. It was later renamed Independence Hall because of its association with the declaration and the Constitution. The building remains part of Independence National Historical Park.
The declaration was adopted in the Assembly Room on July 4, 1776. The same room hosted the Constitutional Convention in 1787, where delegates drafted and signed the United States Constitution. That shared setting makes Independence Hall one of the most important surviving sites of the American founding.
A frequent mix-up is Carpenters' Hall, where the First Continental Congress met in 1774. Federal Hall in New York City was the first U.S. Capitol under the Constitution and hosted George Washington's first inauguration, but it was not the site of the declaration's adoption.
