Sacramento History Museum is the only museum devoted to Sacramento, California and California Gold Rush history. It is located at 101 I Street in Old Sacramento. Just west of the museum is the Sacramento River and both the Tower Bridge and the I Street Bridge are visible from the museum. The building itself is a replica of Sacramento's 1854 City Hall and Waterworks building, showcased in natural brick with two stories of 14 foot double doors across the front. Exhibit themes include the Gold Rush and mining, Nisenan & Maidu Indian Nations, fur trapping, agriculture, and cultural heritage.
