Nicollet Tower & Interpretive Center

Nicollet Tower is a historic observation structure in Sisseton, South Dakota, with a platform that overlooks three different states. The site includes an interpretive center that presents information about the region's geography and history.

French cartographer Joseph N. Nicollet explored and mapped the Coteau Des Prairies region during the 1830s, creating foundational geographic documentation. The tower bearing his name stands as a landmark to this early mapping effort.

The interpretive center displays artworks and maps that connect the region's geographic features with Native American perspectives. Visitors can see how the landscape holds different meanings for different people who have inhabited it.

The tower and interpretive center are open to visitors with no admission fees during the warmer months from mid-May through mid-October. It's best to check current hours before visiting since seasonal operations may vary.

The tower's construction follows a distinctive method developed by local architect Clarence Herges, using Douglas fir poles and cement pillars joined without nails. This simple yet sturdy building technique reflects resourceful engineering choices from that era.
