The Mead Cultural Education Center in Yankton is the new home of the Dakota Territorial Museum and Yankton County Historical Society. Our collections highlight Dakota Territory, Yankton, Yankton County, and Missouri River Valley history. New exhibits will be added to the museum yearly. The Children’s Transportation Museum is the first of its kind in the region. Our winter hours are 10 a.m.-4 p.m., Monday-Friday (closed Wednesday), and 1-5 p.m. on Saturday and Sunday.
