The Idaho State Capitol in Boise is the home of the government of the state of Idaho. Although Lewiston, Idaho, briefly served as Idaho's capital from the formation of Idaho Territory in 1863, the territorial Legislature moved the capital to Boise on December 24, 1864.
Construction of the first portion of the capitol building began in the summer of 1905, 15 years after Idaho gained statehood. Architects were John E. Tourtellotte and Charles Hummel. Tourtellotte was a Connecticut native whose career began in Massachusetts and skyrocketed further when he moved to Boise. Hummel was a German immigrant who partnered with Tourtellotte in 1903. The final cost of the building was just over $2 million; it was completed in 1920. The architects used varied materials to construct the building and their design was inspired by Classical examples.(Wikipedia)
