Independence Hall in Philadelphia is known as the birthplace of both the Declaration of Independence and the U.S. Constitution.
The building was completed in 1753 as the Pennsylvania State House. The Second Continental Congress met there when it debated and adopted the Declaration of Independence in 1776. Eleven years later, delegates met in the same building for the Constitutional Convention and signed the Constitution in 1787.
The structure was called the Pennsylvania State House during those events. The name Independence Hall became common later, reflecting its association with American independence. The building is part of Independence National Historical Park and is a major site connected with America250.
Carpenters’ Hall also hosted an important early meeting: the First Continental Congress met there in 1774. That fact can cause confusion, but it was not the building where the Declaration was adopted or the Constitution was signed.
