Guenther House (Pioneer Flour Mills house and museum)

The Guenther House, located on the San Antonio River at the King William neighborhood, was the home of Carl Hilmar Guenther, who founded Pioneer Flour Mills in 1859. The historic building now operates as a house museum and restaurant that interprets the Guenther family's milling enterprise and local German-Texan history. The property sits adjacent to the original mill site and is associated with the continuous operation of Pioneer Flour Mills.
