Named after the nearby Sisseton Indian Tribe, this historic fort is now a picturesque state park that unfolds the area's past. Walk the grounds where the officers' quarters, stone barracks, powder magazine, guard house, and other buildings that remain from time of the western frontier. This 1864 fort, atop the Coteau des Prairies (or hills of the prairies), was originally a frontier army outpost called Fort Wadsworth. The site was chosen because it provided a strong natural defense, an ample supply of lime and clay for making bricks, an abundance of lake water for drinking and a thick stand of trees for timber and fuel. Regarded as a National Historic Landmark, it has been restored and is now open to the public. Guided tours by fort "soldiers" and others in costume are available. Join the festivities for entertainment, culture and history during the annual Fort Sisseton Historical Festival. The festival features period entertainment and activities and attracts thousands of visitors each year.
