Philadelphia hosted the United States Centennial Exposition, an earlier national anniversary event remembered in America250 history.
The exposition took place in Philadelphia, Pennsylvania, from May 10 to November 10, 1876. It celebrated the 100th anniversary of the Declaration of Independence and occupied a large area in Fairmount Park. More than 10 million visits were recorded during the fair, a remarkable figure for the era.
Philadelphia was a symbolic choice because the Second Continental Congress met there and the Declaration of Independence was adopted in the city. The exposition also presented American industry, agriculture, science, and culture to visitors from the United States and abroad.
The fair included Machinery Hall, Agricultural Hall, Horticultural Hall, and Memorial Hall. Its legacy is closely tied to America’s earlier centennial, while America250 marks the later 250th anniversary in 2026. Philadelphia remains central to national anniversary programming because of its Revolutionary-era sites.
