The corner stone for the new Courthouse was laid on Saturday afternoon July 18, 1914. In the cornerstone were placed various documents and copies of special publications of each edition and the last regular publication of each newspaper of the county.
The Courthouse is a three story fireproof cement and steel building with Bedford Stone exterior. The inside walls are cement and faced with white marble four feet up from the floor with black marble baseboards. All stairs are white marble with wrought iron grill work and oak banisters. The lobby floors on each story are Terrazzo. The office floors were oak (now carpeted) with oak woodwork to match.
The first floor houses the offices for the Treasurer, Emergency Management & Veterans Office, Human Resources, Rest Rooms and a meeting room called the Farmer’s Room.
The second floor houses the offices for the Auditor, Equalization, Clerk of Courts, Register of Deeds and the Commissioners room. The ceiling of the second floor Lobby is open with a wrought iron and oak railing. Looking up one sees a stain glass dome rising from the third floor ceiling.
On the walls of the main entrance stairway one sees large murals on either side depicting early settlers and Indians living along the Sioux river. The original paintings were deteriorating so were repainted in 1970 by George Fergen a local artist.
The third floor contains a large Courtroom, Judges chambers, Jury rooms and a Department of Fish and Games. The walls of the third floor are elaborately decorated with gold leaf and four large paintings depicting Justice in different forms.
