Six miles west of Redding, a row of old, half-ruined, brick buildings remind passing motorists that Shasta City, the lusty "Queen City" of California's northern mining district, once stood on this site. These ruins and some of the nearby roads, cottages, and cemeteries are all silent but eloquent vestiges of the intense activity that was centered here during the California gold rush. Iron shutters still swing on massive, old, iron hinges before the doors and windows of grass-filled, roofless buildings that once were crowded with merchandise, and alive with the human sounds of business, trade, and social endeavor. The County Courthouse is restored to its 1861 appearance, the year when it was converted from commercial uses to become the Shasta County Courthouse. Today the building is filled with historical exhibits, and an unparalleled collection of historic California artwork that make it the central figure of Shasta State Historic Park.

The park offers exhibits, tours, demonstrations, and occasional recreational and educational events.
