Guenther's Upper Mill, Site of
San Antonio, TX
German-trained millwright Carl H. Guenther founded his San Antonio milling operation in 1859 and, in 1868, built this second dam and mill upstream at a spot closer to town. The upper mill served as an outlet for both of his plants before the family consolidated at the downstream Pioneer Flour Mills around 1900. The vacated building later housed a macaroni factory, an ice cream company, and a garage before being razed in 1926.
