In which building was the United States Declaration of Independence adopted in 1776?

The United States Declaration of Independence was adopted in Independence Hall in Philadelphia in 1776.

The building was originally called the Pennsylvania State House. The Second Continental Congress met there when it approved the Declaration on July 4, 1776. The building received the name Independence Hall later, reflecting its connection with the Declaration and other founding events.

Independence Hall also hosted the Constitutional Convention in 1787, where delegates drafted the United States Constitution. That dual association makes the site one of the most important surviving places in the country’s founding history.

The building is sometimes confused with nearby sites in Philadelphia, including Carpenters’ Hall, where the First Continental Congress met in 1774. Independence Hall is the specific building associated with the Second Continental Congress’s adoption of the Declaration.
