Gamble Building and Miner's Bean Kettle
Also known as: Express Office Building; Wells Fargo Building; Raggio Store; Co

Why it's listed
Built between 1848 and 1852 by merchant Alexander Gamble, this large slate stone building on Big Oak Flat's old Main Street holds three commercial suites and a small attached jail room. Brick-lined doorways with iron fire doors, a decorated brick frieze and quoins give it a hint of Italianate design. Beside it stands a wood frame building from about 1870, later known as the Miner's Bean Kettle, which served as a residence, business and restaurant into the 1940s. The stone building housed a general store, an express office used by Wells, Fargo and Company until 1893, and at times a post office, law office, cobbler shop and justice court. It reportedly helped slow the 1863 fire that destroyed much of the town. Few alterations have occurred apart from corrugated metal roofing and siding added around 1900. It is listed for its architecture, its role in early settlement and its place in local commerce. Both buildings are now vacant.
Significance in brief: The stone building is argued to be one of the finest surviving examples of Gold Rush stone commercial architecture, one of only two surviving stone buildings in Big Oak Flat, and one of the oldest in Tuolumne County. It is also significant for its long role in the town's commercial life from the 1850s to the 1930s, including Wells, Fargo and Company's tenancy. The frame building is one of only three pre-1890s wood frame buildings left in town.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.
