Round Mountain, Texas
Round Mountain is a small town in Blanco County, set in the granite-and-limestone hills of Central Texas roughly 38 miles west of Austin. It began as a stage stop on the old mail route between Austin and Fredericksburg and takes its name from a nearby rounded hill. Several early buildings survive from that era, including a restored stagecoach inn and a nineteenth-century church, and the surrounding country is ranchland and Hill Country brush.
