Philadelphia hosted the 1876 Centennial Exposition, the United States’ 100th-anniversary world’s fair.
Officially called the International Exhibition of Arts, Manufactures and Products of the Soil and Mine, the exposition opened in Philadelphia’s Fairmount Park on May 10, 1876. It commemorated the centennial of the 1776 Declaration of Independence and attracted visitors from around the world.
The fair displayed industrial inventions, agricultural products, artworks, and exhibits from many nations. Notable presentations included Alexander Graham Bell’s telephone, the Corliss Centennial Engine, and early industrial demonstrations that showcased the United States’ growing manufacturing strength. The exposition’s grounds also included Memorial Hall, which survives as a major Philadelphia landmark.
Philadelphia was a fitting host because the city had been the meeting place of the Continental Congress and the site where the Declaration of Independence was adopted. The 1876 centennial celebration therefore connected the nation’s revolutionary origins with its technological and economic development.
