What was Independence Hall called when the Declaration of Independence was adopted?

Independence Hall was called the Pennsylvania State House when the Declaration of Independence was adopted.

The Philadelphia building was completed in 1753 as the seat of Pennsylvania’s colonial government. The Second Continental Congress met there, and on July 4, 1776, it adopted the Declaration of Independence in the building’s Assembly Room.

The same building later hosted the Constitutional Convention from May 25 to September 17, 1787. Delegates debated and signed the United States Constitution there, giving the site a connection to both major founding documents.

The name Independence Hall became established later, reflecting the building’s association with independence. It is now the centerpiece of Independence National Historical Park and became a UNESCO World Heritage Site in 1979. Carpenters’ Hall, another Philadelphia meeting place, hosted the First Continental Congress in 1774 but is a different building.
