This site contains the structural remains and buildings of a frontier-era U.S. military post that was constructed between 1840-1842 with the intention of providing a neutral territory for interactions with the Winnebago (Ho-Chunk) People as they resettled from Wisconsin into Northeast Iowa. It was occupied until 1849, when the Winnebago People were again removed from the area, and today is managed by the Iowa State Park system as a historically significant site.
Fort Atkinson is open year-round, with daily hours of 4:30 AM – 10:30 PM. A museum at the site is open by appointment only.
Explore the structures still in existence on the site, including barracks, cannon houses, and a stockade.
