The replica is patterned after the original Dakota Territorial Capitol built in 1862 and torn down in 1886. Yankton was the first capitol of the Dakota Territory from 1861-1883. Displays include photos of old Yankton, maps of the Dakota Territory, a gallery of former Territorial governors, a tribute to the local St. John’s Masonic Lodge, and a quilt highlighting Yankton landmarks. The building is located in Riverside Park, which includes free Wi-Fi, trails, play structures and picnic shelters.
