Historic Fort Snelling [MN]
Completed in 1825, Fort Snelling was originally built to prevent non-U.S. citizens from making use of the Mississippi and Minnesota Rivers. After 1851, the fort served as a supply depot, training center for Union troops, and the headquarters of the Army Department of Dakota.
The fort offers a hands-on educational program; living history tours; day camps based on the pioneer stories of Laura Ingalls Wilder; blacksmithing, bread baking, tea, and hearth baking classes; outreach presentations given by costumed interpreters; lectures; and a picnic area. The website offers a virtual tour.
