Pause along the cobblestones of Commercial Street outside the dignified brick and stone facade of 608 Commercial Street. This historic site represents the literal financial bedrock of the California Gold Rush. In 1854, the federal government established the very first United States Branch Mint right here on this parcel, smelting millions of ounces of raw Sierra Nevada gold dust and nuggets into official United States eagle coins to stabilize the roaring frontier economy.

As production soared beyond all expectations, the mint outgrew the facility and moved to Fifth and Mission Streets, but in 1877 the present structure was erected on the foundation to serve as the United States Sub-Treasury. In the deep subterranean vaults beneath your feet, millions of dollars in solid gold coin and bullion were guarded by armed federal marshals. During the 1906 earthquake and fire, federal troops and mint workers fought valiantly with wet blankets to protect the vaults while surrounding city blocks crumbled in flames.

Look at the handsome arched masonry windows and the refined classical pediment. The building later housed the Pacific Heritage Museum, celebrating the centuries-old cultural and maritime commerce connecting San Francisco with East Asia and the Pacific Rim. The intricate architectural craftsmanship and preserved streetscapes remind every visitor of the city's remarkable ability to reinvent itself after catastrophic disasters while safeguarding its authentic bohemian soul.

Commercial Street itself was originally a wooden pier known as Central Wharf, extending several hundred feet into Yerba Buena Cove during 1849; abandoned Gold Rush ships were scuttled and buried beneath the street fill where you now walk.

Walk west along Commercial Street to Montgomery, then turn north until Columbus Avenue branches northwest to the Sentinel Building.
