Sutter's Fort State Historic Park, State historic park in Sacramento, California, United States

Sutter's Fort State Historic Park in midtown Sacramento contains Sutter's Fort, an adobe structure built from 1839 by Swiss migrant John Sutter as New Helvetia, and the California State Indian Museum. The fort, the first non-Indian settlement in the Central Valley, was restored in 1893 and given to the state of California; California State Parks has operated it since 1947.

John Sutter, a Swiss migrant, built the fort named New Helvetia in 1839; it was the first non-Native community in the Central Valley and a stop on the California and Siskiyou Trails. The fort was abandoned when gold was found near Sutter's sawmill in Coloma in 1848. The original adobe structure was restored in 1893 and given to the state of California; California State Parks has operated it since 1947.

The reconstructed fort is open to visitors and offers guided tours through its buildings and displays. It works best to visit during daytime when rangers are present to provide explanations and demonstrations of 19th-century life.

The fort served as an information center and supply depot for Gold Rush prospectors in 1848 before later being repurposed as a school and storage facility. Many of the structures visible today are reconstructions showing what the original looked like more than 150 years ago.
