What does the Tuolumne County Museum cover?
The Tuolumne County Museum documents the history of Tuolumne County and California from its downtown Sonora home in the old county jail. The Tuolumne County Historical Society’s mission is to discover, collect, preserve and share knowledge about that history.
The Historical Society was established in 1956. Its museum and History Research Center serve scholars, local residents and visitors seeking information about the area. The Research Center is a separate resource for historical research, alongside the museum and Genealogical Society.
The museum is about 0.4 miles from Gold Lodge, where you can book a room at this Sonora lodge. The address appears as either 158 Bradford St. or 58 W. Bradford St., Sonora, CA 95370; verify the street number before travel.
What can you see in the exhibits and local history collection?
The Tuolumne County Historical Society’s collection includes memories and images spanning Gold Rush times through the modern era. The exhibits are housed in a gallery adjoining the jail’s original cell blocks, connecting the displays with the building’s former use.
The jail was built in 1866. After a replacement jail was built one block north, the county designated the older building as the Tuolumne County Museum at the Historical Society’s request. The former jail is both the setting for the collection and part of the county’s history.
How should you plan your visit?
The Historical Society’s schedule has the museum closed Sunday and Monday, open Tuesday 10:00 am–4:00 pm, Wednesday 1:00 pm–4:00 pm, and Thursday through Saturday 10:00 am–3:30 pm. The City of Sonora’s schedule gives daily hours of 11 am–4 pm. Call the Historical Society at (209) 532-1317 to confirm the schedule; check the official site before you go.
The address discrepancy is another reason to confirm your destination before setting out. Since the museum is in downtown Sonora, you can pair it with time in the city centre. The Sonora city centre guide covers local stops.

What else can you combine with a museum visit?
Downtown Sonora is the most direct pairing, since the museum itself is located there. You can make the city centre part of the same outing, then consider the Dragoon Gulch Trail in Sonora as a separate outdoor stop.
The History Research Center supports historical research, while the museum collection brings together memories and images from across the county’s past.
