Forbes Mill is a now-defunct flour mill originally built in 1854 located in Los Gatos, California, which served as the History Museum of Los Gatos after having been saved from destruction in 1982. The museum closed in 2014, and its collections are now part of New Museum Los Gatos. The building is currently owned by the City. The mill is the first commercial building to be established in the city of Los Gatos. The existing two-story building is actually a storage annex, which was added to the original four-story stone mill building in the fall of 1880.
