Nicollet County - A Gateway and a Gathering Place

Nicollet County has been a gateway and a gathering place for thousands of years. The County continues to be an important crossroads today with growing cities, important businesses and industry, recent immigrants, and productive agriculture.

The Nicollet County Historical Society interprets the rich history of our county, the Minnesota River Valley, and our state. Visit us at the Treaty Site History Center, Harkin Store, Fort Ridgely, W.W. Mayo House, Traverse des Sioux Townsite or the E. St. Julien Cox House; come to a program; or search some of our collections here online or in our library.

Thanks for visiting!

** PLEASE NOTE THE NEW WINTERTIME HOURS at the Treaty Site History Center: we will be closed Sundays from November through February and closed December 20, 2015 through January 10, 2016. Archives and group tours available by appointment only.
