Independence Hall hosted both the adoption of the Declaration of Independence and the Constitutional Convention.
The building stood in Philadelphia and was originally called the Pennsylvania State House. The Second Continental Congress met there when it adopted the Declaration on July 4, 1776. From May 25 to September 17, 1787, delegates also met there for the convention that produced the United States Constitution.
The building’s name changed over time. “Independence Hall” became especially associated with the nation’s founding after the American Revolution, while “Pennsylvania State House” describes its colonial and early state-government origins. The same complex also housed Congress and the Pennsylvania legislature during different periods.
Independence Hall is part of Independence National Historical Park and became a UNESCO World Heritage Site in 1979. It is often confused with Federal Hall in New York City, where George Washington took the presidential oath in 1789. Those buildings are linked to the founding era but hosted different events.
