The Calumet Unit of Keweenaw National Historical Park focuses on the preservation and interpretation of buildings and sites associated with the former Calumet & Hecla Copper Mining Company. The U.S. Congress determined that the Calumet area was essential to telling the story of copper mining on the Keweenaw Peninsula.

The corporate-sponsored community planning in Calumet, Michigan, as evidenced in the architecture, municipal design, surnames, foods, and traditions, and the large scale corporate paternalism was unprecedented in American industry and continues to express the heritage of the district. The... picture of copper mining on Michigan's Keweenaw Peninsula is best represented by... the Village of Calumet, (and) the former Calumet & Hecla Mining Company properties.
From the park's enabling legislation.

There are two primary components to the Calumet Unit: The former Calumet & Hecla Copper Mining Company Industrial Operations and Downtown Calumet. Several Keweenaw Heritage Sites are located within the Calumet Unit. These include the Calumet Theatre, Coppertown Mining Museum, Keweenaw Heritage Center and the Upper Peninsula Firefighters Memorial Museum.
