The California State Senate Chambers, State Capitol Building

At the State Capitol, the past, present and future of California interact with equal force. The building serves as both a museum and the state’s working seat of government. Visitors to the Capitol can at once experience California’s rich history and witness the making of history through the modern lawmaking process.

California State Capitol Museum

While the entire building may be considered a museum, the heart of the Capitol Museum can be found on the basement and first floor of the original section of the building. In the basement can be found the tour office (B-27), a small theater showing several short films on the history of the Capitol, the gift shop, and the Arthur Mathews mural, the "History of California." On the first floor, visitors can tour the restored historic offices of the Secretary of State, Treasurer, and Governor of California, as well as two rotating exhibit rooms. In the center of the rotunda stands the marble statue, "Columbus' Last Appeal to Queen Isabella," sculpted by Larkin Mead and given to California by banker and philanthropist D.O. Mills in 1883. The museum offers self-guided and guided tours (normally on the hour), and a chance to see the legislature at work when it is in session.
