Independence Hall

The room where America was declared independent, and the room where its Constitution was written, are the very same room — eleven years apart.^[1]^[1]

About the Place

Why it matters

Independence Hall is a red-brick civic building in Philadelphia, Pennsylvania, built from 1732 to 1753 as the Pennsylvania State House, seat of the colonial legislature.^[1]^[2]

In the building's Assembly Room, the Second Continental Congress adopted the Declaration of Independence on July 4, 1776, formally announcing the thirteen colonies' break from Great Britain.^[1]^{[2, p. 5]}

The Liberty Bell hangs in Independence Hall's bell tower, where it rang out from the steeple built for the old Pennsylvania State House.

Eleven years later, in the summer of 1787, delegates returned to the same room for the Constitutional Convention, drafting the U.S. Constitution that still frames the federal government today.^[1]

The building now forms the centrepiece of Independence National Historical Park.^{[3, p. 2]}

Legacy & Reputation

What’s the verdict?

Legacy & Reputation

What's the verdict?

Independence Hall’s reputation as sacred ground was not automatic. For decades after the Revolution it was ordinary state office space; by an Act of the Legislature of 11 March 1816, the city of Philadelphia acquired the site after the state government had relocated. It was later designated a UNESCO World Heritage Site.^{[2, p. 82]}^{[3, p. 2]}

Myth-buster

Think you know this one?

Myth-buster

Think you know this one?

Myth: the Declaration of Independence was signed inside Independence Hall on July 4, 1776, in one dramatic ceremony. In fact, Congress only adopted the text that day — most delegates signed the engrossed copy weeks later, on August 2.^[4]^{[2, p. 82]}

Quick Facts

The essentials

Quick Facts

Location: Part of United States (built as a British colonial provincial capitol) — today, Philadelphia, Pennsylvania, United States Period: Early Modern World Classification: Institution Also known as: Pennsylvania State House (original name, used until 1824)

Roger would like you to know…

Independence Hall was not built for independence. Ground plans were approved in August 1732 for the Pennsylvania State House, an ordinary colonial government building where loyal British subjects handled provincial paperwork.^[1]

Keith has spotted the problem…

The famous scene of delegates signing the Declaration on 4 July 1776 did not happen. Congress adopted the text that day, but delegates signed the engrossed copy on 2 August instead.^[4]^{[2, p. 82]}

The bell has some explaining to do…

The Liberty Bell's own documented ringing record does not list 4 July 1776 among its calls — it is recorded ringing to proclaim the Declaration on 8 July 1776 instead.^[1]

The name arrived late…

The building wasn't always called Independence Hall. It was known as the State House; the Liberty Bell's own itinerary records show it welcoming Lafayette to the city on 29 September 1824, around the period the newer name began to take hold.^[1]

Keith would like to clarify…

It came close to losing its role as a seat of government: by an Act of the Legislature of 11 March 1816 the city of Philadelphia took over the site after the state government's business had moved on.^{[2, p. 82]}

Meanwhile, in history…

The Declaration's first public reading took place in the State House Yard on 8 July 1776 — independence was announced to Philadelphians four days after Congress adopted it.^[1]^{[2, p. 2]}

Roger insists this matters…

Independence Hall is a UNESCO World Heritage Site, forming the centrepiece of Independence National Historical Park.^{[3, p. 2]}

One chair survived the century…

Almost everything in the Assembly Room today is a careful reconstruction. Only two original features remain: a carved frieze, and the Speaker's chair made by John Folwell in 1779, in which George Washington presided over the Constitutional Convention.

File under: surprisingly true…

The tower's steeple has its own separate history — the book-length history of the Hall devotes chapters to ‘The Steeple removed’ and ‘The Steeple restored’ as distinct episodes.^{[2, p. 82]}

One for the Ageonauts…

From 1794 Charles Willson Peale ran his museum inside the building, and it is remembered for holding a mounted skeleton contemporaries called ‘the Mammoth’ — the birthplace of American independence also housed a giant prehistoric skeleton.^{[2, p. 82]}

I have often and often in the course of the Session, and the vicissitudes of my hopes and fears as to its issue, looked at that behind the President without being able to tell whether it was rising or setting: But now at length I have the happiness to know that it is a rising and not a setting Sun.^{[2, p. 2]}

Benjamin Franklin

Recorded as the last delegates signed the Constitution in the Assembly Room on 17 September 1787 — the date the Constitution's own closing text gives; Franklin was gesturing at the sun carved into the back of the presiding chair.^[5]
