Guenther House at Pioneer Flour Mills

Guenther House occupies the riverside site of Pioneer Flour Mills, established by Carl Hilmar Guenther in 1859, and now operates as a house museum and restaurant documenting the mill's history. The property preserves original mill-era structures and displays related artifacts about flour milling in San Antonio. Located on a quiet bend of the San Antonio River in the King William neighborhood, the museum and mill storefront are frequently overlooked by visitors focused on larger downtown attractions.
