Guenther House, San Antonio

The Guenther House is a restaurant, museum and a store located in the King William neighborhood at the intersection of King William and Guenther streets. Currently operated by C. H. Guenther and Son. Inc., the home was originally built as a private residence by Pioneer Flour Mills founder, Carl Hilmar Guenther.

This vernacular native limestone home was one of the first built in the neighborhood in 1859. The stones were quarried in the area that is now Brackenridge Park, and the wood used in the construction was East Texas pine. The original entrance to the house faced southward towards the mill.

A 1915 expansion of the house changed the entrance to the north side, fronting the San Antonio River. The original entrance now serves as a hallway between the museum and the River Mill Store part of the house. The top floor, known as the Roof Garden, once hosted dances. Presently, the space is used for large meetings or luncheons. The south side of the house today has a patio and arbor for outdoor dining.

An area of the house, that once served as the library, is now the museum containing family keepsakes, as well as artifacts of milling, dining and baking history in San Antonio. Travel souvenirs from around the world are also part of the museum. The museum, store and restaurant are open to the public 7 days a week.

The property was listed on the National Register of Historic Places listings in Bexar County, Texas on October 11, 1990.
