Fairmount Park hosted Philadelphia’s 1876 Centennial Exposition, the first major world’s fair held in the United States.
The exposition occupied about 450 acres in the western section of Fairmount Park, near the Schuylkill River. It opened from May 10 to November 10, 1876, and celebrated the centennial of the Declaration of Independence while showcasing industrial, agricultural, artistic, and technological achievements.
More than nine million visits were recorded during the fair. Exhibits included the Corliss steam engine, Alexander Graham Bell’s telephone demonstration, machinery, artworks, and displays from countries around the world. The event helped present Philadelphia as a center of American industry and culture.
Several buildings were temporary, but Memorial Hall survived and later became the Please Touch Museum. The exposition site also influenced the development of the surrounding park. It is sometimes confused with Independence Hall, which was central to Philadelphia’s revolutionary history but was not the exposition grounds.
