Independence National Historical Park, Philadelphia, Pa

In Short

Edward M. Riley’s historical handbook presents the origins, evolution, and preservation of Independence National Historical Park in Philadelphia. It traces how the Pennsylvania State House hosted both the Second Continental Congress and the Constitutional Convention, sheltering the core decisions that birthed the United States. Beyond its Revolutionary period, the narrative follows the physical architecture through cycles of decay, adaptive reuse, and eventual restoration. It highlights key neighborhood landmarks and the symbolic rise of the Liberty Bell, explaining how municipal property became a protected federal shrine to self-government and human liberty.

The Story

The narrative begins in the 1730s with the construction of Pennsylvania’s Provincial State House. Designed to serve local legislative needs, the central hall was soon supplemented by wing buildings erected to safeguard provincial records. Despite initial reluctance from local officials, these offices housed colonial agencies, the Library Company of Philadelphia, and visiting Indian delegations. To mitigate fire hazards caused by occupants, separate wooden structures were eventually erected nearby, and vacant lots at Fifth and Sixth Streets were designated for future municipal developments.

As tensions with Great Britain escalated in the 1770s, Philadelphia’s central geographic location made it the natural hub for intercolonial governance. The First Continental Congress convened at Carpenters’ Hall in 1774 to petition the British King and organize economic boycotts. By 1775, representatives gathered in the State House Assembly Room, where they voted to adopt the Declaration of Independence on July 4, 1776. The building served as the seat of government throughout the American Revolution, save for periods of grave danger such as the British occupation during the winter of 1777–1778. Congress returned to celebrate news of Yorktown in 1781, receiving captured British colors inside the chamber.

Postwar economic depression and regional unrest highlighted the weaknesses of the Articles of Confederation. In May 1787, fifty-five delegates assembled in the same State House chamber for the Federal Constitutional Convention. Over a long summer, they debated and crafted the United States Constitution, fashioning a flexible framework for federal self-government. When the federal capital temporarily relocated to Philadelphia from 1790 to 1800, Congress occupied the adjacent County Courthouse, while the U.S. Supreme Court met in the newly constructed City Hall.

When government offices departed for Washington and Harrisburg in 1800, the vacant State House faced uncertainty. Parts of the building housed Charles Willson Peale’s natural history museum, federal courtrooms, and municipal councils. Outside, Samuel Vaughan redesigned the overgrown State House Yard into a landscaped park, and William Strickland replaced the original tower with a restored steeple in 1828. Popular veneration grew through the nineteenth century, sparked by events like Lafayette’s 1824 visit and the rising symbolic prominence of the State House Bell—dubbed the "Liberty Bell" by anti-slavery activists in 1839.

Restoration efforts accelerated late in the nineteenth century, spearheaded by civic groups, the Daughters of the American Revolution, and the American Institute of Architects. Surrounding structures were rehabilitated to reflect their eighteenth-century appearance. Finally, through mid-twentieth-century legislation and cooperative agreements between the City of Philadelphia and the National Park Service, the surrounding urban blocks were combined into Independence National Historical Park to preserve these structures for future generations.

How It Unfolds

The provincial beginnings Constructed in the 1730s as the Pennsylvania State House, the complex quickly expands to include wing buildings for government records and visiting delegations. The Assembly reserves adjacent lots for future civic buildings, laying the ground plan for the city's political center.

The revolutionary crucible American delegates gather in Philadelphia as conflict with Britain deepens, convening the Continental Congress inside the State House Assembly Room. There, leaders vote to adopt the Declaration of Independence in 1776 and govern through the difficult years of war.

The constitutional compromise Fifty-five state delegates assemble in 1787 to address the political weaknesses of the Articles of Confederation. Meeting in secret session, they craft and sign the United States Constitution, creating a central federal government balanced by state interests.

The temporary national capital Under the Residence Act of 1790, federal governance sits in Philadelphia for a decade, with Congress meeting in Congress Hall and the Supreme Court in City Hall. Important precedent-setting acts and the inauguration of John Adams occur within the complex.

The shift to preservation After government offices vacate the site in 1800, the State House hosts museums, local courts, and civic events while its grounds are landscaped. Mid-century veneration renames the hall and protects the surrounding historic buildings from slated demolition.

The creation of a national shrine Civic organizations and architects restore the Independence Hall group to its eighteenth-century appearance between 1896 and 1934. In 1951, custody transfers to the National Park Service, formalizing the site and its surrounding historic neighborhood as a federal park.

The People

• George Washington serves as the presiding officer of the Federal Constitutional Convention of 1787. His presence and endorsement provide essential legitimacy to the proceedings, helping secure public confidence in the newly drafted Constitution.
• James Madison acts as a central floor leader during the Constitutional Convention. He works tirelessly to draft, debate, and shape the core mechanisms of the federal government, emerging as one of its primary intellectual architects.
• Benjamin Franklin operates as the elder statesman and peacemaker among competing factions at the 1787 convention. Earlier, his diplomatic efforts in France secure the alliance that brings crucial military support to the Revolutionary cause.
• James Wilson collaborates closely with Madison on the convention floor, exercising a powerful direct influence on the finished text of the Constitution while championing a strong national framework.
• Charles Willson Peale operates a natural history museum and portrait gallery on the upper floor of the State House during its post-capital period, while personally maintaining and landscaping the State House Yard to protect it from neglect.
• Samuel Vaughan directs the initial systematic landscaping of the State House Yard in 1784, transforming a neglected military ground into a structured public park featuring serpentine paths and broad elm-lined walks.

In Its Own Voice

"The United States was created in Philadelphia on July 4, 1776, when the Continental Congress voted the final form of the Declaration of Independence."

Carl van Doren succinctly captures the foundational historical moment that transformed a colonial state house into a national origin point.

"The trees are yet small, but most judiciously arranged."

The Reverend Manasseh Cutler records his impressions of the newly landscaped State House Yard in his personal journal, noting Hogarth's influence on the winding pathways.

"It was that which gave promise that in due time the weights should be lifted from the shoulders of all men, and that all should have an equal chance."

What It's Really About

The text examines how physical structures become repositories of national identity, shifting in meaning as historical memory evolves.

The narrative highlights the fragile nature of historic preservation, showing that crucial buildings survived through a mix of accidental utility, civic pride, and dedicated preservation campaigns. At its core, the work explores how the abstract concepts of liberty and federal union took concrete root in specific rooms, furniture, and cast metal, transforming localized municipal architecture into broad symbols of democratic governance recognized across the world.
