Vandalia State House
The Vandalia State House, the fourth Illinois statehouse, served as the capitol from 1836 until 1839 and is the oldest surviving capitol building in the state. The first floor contains a large entry hall and rooms representing the offices of the Auditor, Treasurer, and Secretary of State, as well as the Supreme Court chamber. The second floor is composed of a central hall and recreated House and Senate chambers, each of which contains a visitor gallery reached by staircases.
The site offers an exhibit, tours, and occasional recreational and educational events.
