Independence Hall was originally the State House for the Province of Pennsylvania. In 1729 the provincial assembly set aside funds for the building, designed by lawyer Andrew Hamilton. Three years later, construction began under the supervision of master carpenter Edmund Wooley. In 1736 the assembly moved into the statehouse, which was not fully completed until 1756.

As American opposition to British colonial policies mounted, Philadelphia became a center of organized protest. To decide on a unified course of action, in 1774 the First Continental Congress met in newly finished Carpenters’ Hall, whose erection the Carpenters’ Company of Philadelphia had begun 4 years earlier. In 1775 the Second Continental Congress, taking over the east room of the ground floor of the statehouse from the Pennsylvania assembly, moved from protest to resistance. Warfare had already begun in Massachusetts. Congress created an Army and appointed George Washington as commander in chief. Yet the final break with the Crown had not come; not until a year later would independence be declared.

On July 2, 1776, Congress passed Richard Henry Lee’s resolution of June 7 recommending independence. The Delegates then turned their attention to Thomas Jefferson’s draft of the Declaration, which had been submitted on June 28. After modification, it was adopted on July 4. Four days later, in Independence Square, the document was first read publicly, to the citizens of Philadelphia. In a formal ceremony on August 2, about 50 of the 56 signers affixed their signatures to the Declaration; the others apparently did so later.

Long, hard years of war ensued. In the late autumn and winter of 1776–77, the British threatened Philadelphia and Congress moved to Baltimore. Again in the fall of 1777 it departed, this time for York, Pa. During the British occupation of Philadelphia that winter and the next spring, the redcoats used Independence Hall as a barracks and as a hospital for American prisoners. In the summer of 1778, the Government returned. On November 3, 1781, Congress officially received news of Cornwallis’ surrender at Yorktown. Independence practically had been won.

Earlier that same year, the Articles of Confederation and Perpetual Union had gone into effect. Under the Confederation, Congress stayed in Philadelphia until 1783, and later met in other cities. In 1787 the Constitutional Convention also held its highly secret sessions in Independence Hall, in the same chamber in which the Declaration had been adopted.

About the same time that Philadelphia became the second Capital (1790–1800) under the Constitution, after the Government had moved from New York City, Independence Hall acquired three new neighbors in Independence Square: City Hall (1791), on the east; County Court House (1789), on the west; and American Philosophical Society Hall, on the southeast. Beginning in 1790, Congress met in the County Court House (subsequently known as Congress Hall). The following year, after sitting for a few days in Independence Hall, the U.S. Supreme Court moved to City Hall. In 1793 George Washington was inaugurated for his second term as President in Congress Hall, and 4 years later President Adams also took his oath of office there.

In 1799 the State government vacated Independence Hall and moved to Lancaster. The next year, the Federal Government relocated to Washington, D.C. The city of Philadelphia then used City Hall and Congress Hall, and various tenants occupied Independence Hall until the city acquired it in 1818. For example, during the period 1802–27 artist Charles Willson Peale operated a museum there. He and his son painted many of the signers and heroes of the War for Independence. These portraits form the nucleus of the park’s present collection, which is exhibited in the Second Bank of the United States Building; a special room is devoted to the signers.

Stately and symmetrical Independence Hall, a 2½-story red brick structure that has been carefully restored, is the most beautiful 18th-century public building of Georgian style in the United States. The tall belltower, reconstructed along the original lines in 1828 by architect William Strickland, dominates the south facade. Smaller two-story, hip-roofed, brick wings, erected in 1736 and 1739 and restored in 1897–98, one of which serves as a park information center, are connected to the main building by arcades.
