The 400th anniversary of explorer Christopher Columbus’s arrival in the Americas was commemorated in 1893 by the World’s Columbian Exposition in Chicago, Illinois. The exposition, attended by millions, was also known as the White City after its central white buildings set along canals. The first view visitors had was of the domed administration building, shown here, which was designed by New York architect Richard Morris Hunt in the Beaux-Arts style. This style, named after the École des Beaux-Arts in Paris where Hunt and other architects of the exposition studied, had a significant impact on American architecture over the next several decades.
