The World's Columbian Exposition (the official shortened name for the World's Fair: Columbian Exposition, also known as The Chicago World's Fair) was a World's Fair held in Chicago in 1893 to celebrate the 400th anniversary of Christopher Columbus's arrival in the New World in 1492. The iconic centerpiece of the Fair, the large water pool, represented the long voyage Columbus took to the New World. Chicago bested New York City; Washington, D.C.; and St. Louis for the honor of hosting the fair. The Exposition was an influential social and cultural event and had a profound effect on architecture, sanitation, the arts, Chicago's self-image, and American industrial optimism. The Chicago Columbian Exposition was, in large part, designed by Daniel Burnham and Frederick Law Olmsted. It was the prototype of what Burnham and his colleagues thought a city should be.
