The Declaration of Independence was adopted in Philadelphia's Independence Hall, the historic site associated with the America250 anniversary.
The building was originally known as the Pennsylvania State House. The Second Continental Congress met there when it approved the Declaration of Independence in 1776, and the Constitutional Convention met there in 1787.
The name Independence Hall became common later, reflecting the building's association with the Declaration. It stands in Independence National Historical Park in Philadelphia and is recognized as a major symbol of American founding history.
Carpenters' Hall hosted the First Continental Congress in 1774, which is a common source of confusion. Federal Hall in New York City was the first U.S. Capitol under the Constitution, while Congress Hall in Philadelphia served as the meeting place of the U.S. Congress from 1790 to 1800.
