Marshall Gold Discovery State Historic Park in Coloma is the site of the 1848 gold discovery that changed the course of history of California and the nation. Outdoor exhibits include a replica of the original sawmill where the first gold flake was found, original indigenous grinding rocks, and over 20 historic buildings that include miners’ cabins, a Chinese store, a one-room schoolhouse, churches, homes and businesses. Our museum houses artifacts belonging to James Marshall, the gold discoverer. We have a hilltop monument, blacksmith shop with live demonstrations, and a Gold Rush Research Library that houses journals, books, maps, and images focused on the California Gold Rush and peoples of Coloma.
