What was the original name of Independence Hall when Congress adopted the Declaration in 1776?

The original name of Independence Hall was the Pennsylvania State House.

The building in Philadelphia was completed in 1753 as the seat of Pennsylvania's colonial government. The Second Continental Congress used it during the American Revolution, and Congress adopted the Declaration of Independence there on July 4, 1776. The building also hosted the Constitutional Convention in 1787.

It became known as Independence Hall during the nineteenth century, after the events associated with independence had made the building nationally symbolic. Its central Assembly Room is the setting most closely connected with the Declaration and the Constitution. The building's earlier official name reflects its origin as a colonial statehouse rather than a purpose-built national monument.

The site is part of Independence National Historical Park and is recognized as a UNESCO World Heritage Site. Its connection to both independence and the later federal Constitution makes it especially prominent in commemorations of the United States' founding era and 250th anniversary.
