It extends and updates a 1974 listing and contains 207 contributing and 90 noncontributing resources.","why_significant":"The district reflects Mason's growth from the 1851 Fort Mason frontier post into a county seat serving ranching and agriculture. Its buildings share a distinctive masonry tradition, often using red sandstone salvaged from the abandoned fort, with beaded mortar joints and German-influenced vernacular forms. The form also presents it as an example of rural settlement and urban development in Texas.","narrative":"Mason's historic district covers roughly 250 acres in the Texas Hill Country, centered on the 1909 Classical Revival courthouse and its square. It also includes the commercial streets, large-lot residential neighborhoods and the hilltop site of Fort Mason, established in 1851. After the fort was abandoned in 1869, its dressed and rubble sandstone was reused in many local buildings, giving the town a distinctive masonry character. Dark red sandstone with contrasting white beaded mortar joints appears on the 1894 county jail and an 1879 commercial building, while limestone, brick, concrete block and frame construction also appear. German influence shows in Fachwerk houses, and Queen Anne, Italianate, Tudor Revival and Bungalow styles are present. The town grew as a stage stop and a service center for ranchers and farmers, and the district records development from the 1860s to 1941. Low density, irregular lots and a diagonal highway give Mason a rural, informal feel.","period_of_significance":"to 1941 (start date not clearly stated in the available text)","architect_builder":"Fredrick Dose and James Mullins (second courthouse, 1877); August Brockmann (first courthouse, 1872); L.T.
