Arizona State Capitol

The Arizona Territorial - 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 a focus on the history and culture of Arizona. The Arizona State Library, which occupied most of the 1938 addition until July 2017, re-opened in late 2018 as a part of the Arizona Capitol Museum.
