In which Philadelphia building was the Declaration of Independence adopted?

The Declaration of Independence was adopted in Independence Hall in Philadelphia.

The building was completed in 1753 as the Pennsylvania State House. The Second Continental Congress used its Assembly Room when it debated and adopted the Declaration in 1776. The Constitution was also drafted and signed there in 1787, making the building central to two foundational moments in United States history.

The building was originally called the Pennsylvania State House. The name Independence Hall became common later, reflecting the site’s association with the Declaration and the creation of the new nation. Its bell tower once housed the Liberty Bell, another object strongly connected with American independence.

Independence Hall is part of Independence National Historical Park, which preserves numerous sites in Philadelphia. The complex is not the same building as Congress Hall, where the federal Congress met in the 1790s, or Federal Hall in New York City, where George Washington took the presidential oath.
