Castroville, Texas
Castroville lies along the Medina River in Medina County, about 22 miles west of San Antonio at the edge of the South Texas plains. The town was settled by immigrants from the Alsace region and is widely known as the "Little Alsace of Texas," a heritage still visible in its early limestone-and-timber houses and steep-roofed cottages. Alsatian customs and architecture continue to shape the town's identity, setting it apart from the surrounding ranch country.
