San Francisco Mint

The San Francisco Mint is a coin production building in San Francisco, United States, constructed in the neoclassical style from 1937. Large stone columns mark the entrance, while symmetrical windows and a rectangular floor plan reinforce the formal design.

The mint opened in 1854 to convert gold discoveries from the California Gold Rush into official United States currency. The current building arose after reconstruction in the 1930s and replaced an older structure damaged by earthquakes.

The building earned the nickname "Granite Lady" because of its solid stone construction and still recalls the importance of gold processing in early California. The architecture conveys a sense of government authority and economic stability in a region shaped by the Gold Rush.

The facility sits in central San Francisco and offers guided tours where visitors can learn about coin production. Advance registration is usually required since the rooms have limited access.

During its active years, the building stored substantial amounts of gold and silver before operations were relocated for security reasons. Today it mainly houses administrative offices and is rarely open to the public.
