There are ten buildings in the district: the Machine Shop, the "Blacksmith Shop," (misidentified as such; actually the Pipe Shop), the Roundhouse, Warehouse #2, the Superior Boilerhouse, the Gearhouse, the General Office Building, the Library, the Bathhouse, and the Miscowaubik Club.
 These structures, constructed primarily during the 1880s, represent the second generation of mine buildings constructed at the site; the earliest structures were destroyed by fire or razed.
 These buildings are part of a larger industrial complex of mine-related buildings, originally built by the Calumet and Hecla Mining Company, that still stand in the area along Calumet Avenue and Mine Street.
