Independence Hall's history
Independence Hall, initially called the Pennsylvania State House, is a historic civic building in Philadelphia, Pennsylvania. It was constructed in 1732 and completed in 1753 (or 1756, according to another source). It served as the first capitol of the colonial-era Province of Pennsylvania.
The building was designed in the American Georgian style, characterised by exposed brick, clean lines, symmetry, and proportions. The architecture aimed to create a generous sense of space and natural light. The main building had a decked gable roof, balustraded between the chimneys, and a centrally located cupola. The first floor contained two chambers, each about 40 feet square, separated by a spacious centre hall about 20 feet wide. The building was heated by open fireplaces, which were later replaced by stoves. In 1750, a tower was erected to house a staircase and belfry, and in 1777, the State House bell (now called the Liberty Bell) was hung.
Independence Hall is most famous for being the site of several significant events in American history. From May 10, 1775, to 1783, it served as the principal meeting place of the Second Continental Congress, a body of representatives from each of the thirteen British North American colonies. On June 14, 1775, delegates of the Continental Congress, gathered in the Assembly Room and established the Continental Army, appointing George Washington as its commander-in-chief.
On July 4, 1776, the Declaration of Independence was unanimously approved in the Assembly Room of Independence Hall. The Declaration was read aloud to the public in the area now known as Independence Square. This document unified the colonies in North America, declaring their independence from the Kingdom of Great Britain and explaining their justifications. The Liberty Bell is believed to have rung to celebrate this occasion.
From May to September 1787, Independence Hall hosted the Constitutional Convention, where the U.S. Constitution was debated, drafted, and ratified. The Constitution was signed in the Assembly Room on September 17, 1787.
The history of Independence Hall can be divided into four periods: its construction and function as the Pennsylvania State House from 1732 to 1799; its use as a museum from 1802 to 1828; its role as a municipal building from 1818 to 1895; and its transformation into an important historical landmark from 1898 to the present.
Today, Independence Hall is a UNESCO World Heritage Site and a National Historic Landmark. It is open to the public for tours, and visitors can see the room where the United States of America was born, as well as the only original piece of furniture remaining in the Hall, a high-back chair with a gilded sun carved at the top.

Independence Hall's architecture
Independence Hall, originally known as the Pennsylvania State House, is a historic civic building in Philadelphia, Pennsylvania. It is one of the most recognisable buildings in the United States and an example of American Georgian architecture.
Construction of Independence Hall began in 1732 and was completed in 1753 or 1756, serving as the first capitol of the colonial-era Province of Pennsylvania. The building was designed to create a generous sense of space and natural light, with exposed brick creating clean lines, proportions, and symmetry. The foundation was made of rubble stone and lime mortar, while the interior frame and roof trusses were constructed with wooden girders and beams, reinforced with iron plates and pins. The outer shell was built from hard-burned brick, 22 to 23 inches thick.
The Assembly Room is the heart of Independence Hall, where the Declaration of Independence and the Constitution of the United States were debated, drafted, and adopted by the Founding Fathers. The room has undergone several alterations over the years, with wood panelling, furnishings, and paint colours being changed multiple times. During a restoration in 1897-98, the original entablature in the Supreme Court Chamber was removed to lower the ceiling, and the Mills buildings were torn down and replaced with inaccurate replicas. In 1948, the building's interior was restored to its original appearance, and another restoration project began in 2025.
Independence Hall is now a National Historic Landmark and a UNESCO World Heritage Site, open to the public for tours. Visitors can stand in the very room where the United States of America was born and see the only original piece of furniture that remains in the building—a high-back chair with a gilded sun carved at the top.
