Knight Foundry, set in the heart of Sutter Creek, California, is one of America’s last water-powered foundry and machine shops, and one of the nation’s best preserved 19th-century industrial complexes. Established in 1873 by Samuel Knight, this extraordinary facility includes historic equipment and machinery, still in place in its original context. The Knight Foundry complex is always open to the public on the second Saturday of every month. Visitors can interact with knowledgeable and interesting docents, some of whom actually worked at the Foundry before it ceased operations in 1996. The Foundry serves as an educational resource providing a unique window into California’s history and heritage. The preservation and restoration of Knight Foundry provides an unparalleled opportunity to protect the history of industrial technologies as they were traditionally implemented, and to pass them on to future generations.
