The eastern portion of this building was erected in 1884, according to the legend on the facade and a mercantile and hide-buying business at first. An early Coca-Cola bottling plant was located here, but in 1929, William Koock bought the business and switched to Dr Pepper. Before World War I the German American National Bank operated here, expeditiously changing its name to Mason National Bank once hostilities began between the United States and Germany. Hill Country Telecommunications is currently working with their architect to finish out their local offices here, offering internet, Voice Over IP, and many other broadband services.
