Discover the rich cultural heritage of the Northern Plains at Double Ditch Indian Village State Historic Site, located along ND-1804 in Bismarck, North Dakota. This fascinating site offers a glimpse into the lives of the Mandan people who inhabited the area from about 1490 until 1785. Visitors can explore the expansive site which features the remains of two concentric earthworks and numerous depressions, once the foundations of earth lodges. These relics tell the story of a flourishing community and their innovative settlement patterns.

Ideal for history enthusiasts and those looking to learn more about indigenous cultures, the site provides educational opportunities through informative signage and occasional interpretative sessions led by knowledgeable guides. The serene setting along the Missouri River also makes it a wonderful spot for nature lovers to enjoy a peaceful walk while contemplating the landscape that supported a vibrant social and economic center centuries ago.
