The Arizona State Capitol in Phoenix, Arizona, United States, was the last home for Arizona's Territorial government, until Arizona became a state in 1912. Initially all three branches of the new state government occupied the four floors of the statehouse. As the state expanded the branches relocated to adjacent buildings and additions. The 1901 portion of the Capitol is now maintained as the Arizona Capitol Museum with the mission to Connect People to Arizona Government - Past and Present.(Wikipedia)
