Philadelphia, Pennsylvania, USA, United States of America
Independence Hall is a Georgian-style brick building in Philadelphia where the Declaration of Independence was adopted on 4 July 1776 and where the United States Constitution was drafted and signed in 1787. These two events, occurring in the same room eleven years apart, make the building the most politically significant single structure in American history and one of the most consequential in world history. The constitutional framework developed in its Assembly Room has influenced the design of democratic governments on every inhabited continent. It is, in a precise and literal sense, where American democracy was invented.
Built 1732–1753; Declaration of Independence signed 1776; Constitution signed 1787; National Historic Park established 1948; UNESCO inscribed 1979
