The Three Affiliated Tribes Museum is a heritage center honoring the Mandan, Hidatsa, and Arikara tribes who once dominated the Great Plains. Located in New Town, North Dakota, the museum sits near the Missouri River and the location where Lewis and Clark passed through in the spring of 1805 after wintering at Fort Mandan. The information and geographical knowledge provided by the Mandan, Hidatsa, and Arikara Tribes were essential to the survival of the Corps of Discovery.

Thanks in large part to the work of Helen Gough of the Arikara tribe, the museum opened its doors in 1964. Many of her personal items are on display, including ceremonial garb and beadwork. In keeping with her desire to preserve the native traditions and history that were quickly being lost to time, the museum commemorates the culture, heritage, lifestyle, and art of the of the Three Affiliated Tribes, as well as the natural history of the region.

Unique insights shared by staff help engage visitors in an educational experience perfect for all ages. Visitors will also find a historical marker pertaining to Lewis and Clark can be observed outside the museum. Although photography is prohibited inside, a gift shop offers unique and original Native American-made crafts.
