The Idaho State Capitol, located in Boise, was completed in 1912. The building is made out of four different types of marble, including red marble from Georgia, gray marble from Alaska, green marble from Vermont, and black marble from Italy. The capitol building also contains a plaster replica of the marble statue of Nike of Samothrace.
