The first U.S. military post west of the Missouri River, Fort Atkinson was established in 1820 on recommendation of the Lewis and Clark Expedition. Located at Fort Calhoun, the fort was important to the early fur trade, river traffic and Indian relations.
Much of the historic outpost has been reconstructed, and interpretive work continues. Living history demonstrations are scheduled periodically during the summer.
