The Idaho Building in Boise is not the only structure named "Idaho Building." In 1913 an Idaho Building opened in Meridian, Idaho. An Idaho Building represented the state of Idaho at the 1893 World's Columbian Exposition in Chicago; an Idaho Building won second place at the 1904 Louisiana Purchase Exposition in St. Louis; and an Idaho Building won a gold medal at the 1905 Lewis and Clark Centennial Exposition in Portland.
