The State Capitol Historic Site interprets the history of the Capitol and state government, both historical and current. The Capitol teaches the political process and inspires citizen participation in government.

The Capitol became part of the Minnesota Historical Society's historic site program in 1969. MNHS is responsible for the Capitol's furnishings and artwork, and oversees preservation work, leads tours of the building, and provides special events and educational programs.

As stewards of the historic building, the Capitol staff strive to preserve and restore Cass Gilbert's original architecture and artistic vision for future generations.

The Minnesota State Capitol was listed on the National Register of Historic Places in 1972.
