History Center is open. The Archives requires an appointment. Call 507-934-2160.



Beginning Saturday, March 5, 2022, masks will be encouraged but not required for all visitors regardless of vaccination status. This change is because the Centers for Disease Control (CDC) lowered the COVID-19 Community Level to a “Low” level from the “High” level of transmission that we have experienced for several months.

Masking will continue to be highly recommended but not required for NCHS staff, volunteers, and interns. Masks will continue to be available for our team and visitors. NCHS staff require masks in areas where adequate physical distancing is not possible, such as in confined spaces or in areas with limited air circulation.


Keeping us all safe.

Our staff reserve the right to request masking in areas where social distancing is unavailable, in confined spaces, or in areas with limited air circulation.
Strongly encourage keeping your distance from others
Enhanced cleaning of high-touch surfaces and providing hand-sanitizing stations for visitors.
If you feel sick, have flu-like symptoms, or have been in contact with someone who has recently had COVID-19, please visit us another time.

During your visit.

Admission to the museum gives you access to all exhibits, including the Treaty of Traverse des Sioux, Educational Excellence, Fort Ridgely, and others coming in April.

Please note: The Research Center is open but requires masks and an appointment. Make an appointment with the Research Coordinator. Online research services are also available.
