The exposition spanned 690 acres (2.8 km²) and showcased nearly 200 newly constructed, though temporary, buildings that primarily reflected neoclassical architecture.

The fairgrounds also included intricate canals, lagoons, and representations of people and cultures from 46 different countries. During its six-month duration, the exposition attracted over 27 million visitors.

Its immense scale and breathtaking grandeur surpassed previous world’s fairs, establishing it as a symbol of America’s rising prominence on the global stage.

Nearly 129,000 people — “a surging sea of humanity,” as the title on this stereograph print describes it — filled the grounds on the opening day of the World’s Columbian Exposition, the most famous world’s fair in America.
