Early Llano County leader, Robert Flack (Bob) Rowntree (1847-1893), built this majestic two-story house in the Prairie Mountain community from 1875 to 1888. Scottish architect John K. Finlay, a pioneer in the Texas granite industry, designed the home using local red-brown sandstone obtained nearby and white limestone from Burnet County. Built with 20-inch thick walls, the house contains eight rooms, each with a fireplace, and porches on both floors overlooking Prairie Mountain and Rough Mountain. Rowntree lived on his 8500-acre ranch with his family until his untimely death on July 19, 1893. Some believe his involvement in the Hoodoo War was connected to his death. Later, the house became the home of Ernst and Lucy (Meusebach) Marschall. Recorded Texas Historic Landmark - 2016
