In 1863, Lewiston, Idaho was the original site of the capitol until Boise was made the capital of the state in 1890 - also the year when President Benjamin Harrison signed Idaho into statehood. A few years after Idaho gained statehood the construction on the original capitol building began in the summer of 1906. The architects who developed the building were John E. Tourtellotte and Charles Hummel. The final cost of the building was approximately $2,098,455.05 and it was completed in 1920.  The architects used several different materials to construct the building and their architecture was inspired by various sources and cultures.
