San Antonio: Guenther House Museum

A master millwright in Germany, Carl Hilmar Guenther sailed for Indianola, Texas, in 1851, and made his way to Fredericksburg, where he was amazed at the lack of facilities to process grains. So, being an industrious German, he built his first mill south of Fredericksburg, where it remained for eight years. Occasional droughts and floods forced him to move the operation to San Antonio. Guenther built his new mill on the banks of the San Antonio River. Pioneer Flour Mills, as it was known, flourished, enriching the Guenther family for more than a century afterward.

Guenther built a large home in 1860 in the largely German King William District adjacent to his mill. The repurposed home, which is open to the public, contains a popular restaurant, the River Mill Store, conference rooms, and a museum.
