Rustic industrial Knights Foundry is open for self guided tours. If you want to see the metal works, then it’s 2nd weekend of each month. Awesome friendly stuff
Extremely interesting tours are available. Check their schedule for availability.
An AMAZING place to visit for their tour. They also provide blacksmithing classes, offer memberships and are run by volunteers. Definitely plan to give them a visit while you visit downtown Sutter Creek. Check their website for when their tours are.
