Sisseton-Wahpeton Oyate Tribal Administration Building

Sisseton, SD

This $20.4 million administration building was built on 20 acres of tribal-owned land and serves as the official headquarters of the Sisseton-Wahpeton Oyate Tribal Government. Designed to reflect the tribe’s culture and traditions, the building’s circular shape mimics the sacred hoop arrangement of traditional Sisseton-Whapeton villages, while the decorative band around the exterior façade evokes the colored beadwork on women’s traditional dresses. The ceremonial open-air courtyard proudly features a teepee suspended from the skylight.
