Idaho State Capitol’s internal dome is supported by Corinthian marble columns and surrounded by windows in the cupola because the architect insisted on flooding the interior with light. It works so well that staff can tell time by the light’s position. This view from the rotunda shows some of the thirteen stars, which represented the colonies, and many of the 43 smaller stars that represented the states when Idaho joined in 1890. During restoration, a material called scagliola was added to the dome. It matches the marble yet glows in the dark so it’s now called “Capitol of Light.”
