Their stone construction differs from many Central Texas towns, where brick was more common. The buildings record the town's commercial growth, its later decline after 1900, and its businesses such as the broom factory, drug stores and hardware stores.","narrative":"Round Rock's downtown commercial core is a group of about 25 small stone buildings along East Main Street, with one on South Mays Street, built mostly between 1876 and the early 1900s. The town was platted in 1876 as New Round Rock, south of Brushy Creek, to coincide with the southern end of a railroad line, and a building boom produced stone stores, offices, saloons and lodge halls. Load-bearing limestone walls and simply detailed parapets give the street a consistent look that differs from the brick towns elsewhere in Central Texas. Notable examples include the Old Broom Factory, whose maker won a gold medal at the 1904 St. Louis World's Fair, the Otto Reinke Building, the Masonic Lodge building of 1878, and the Economy Drug Store with its intact early interior. Nelson Hardware has a cast-iron and pressed-tin front dated 1900. Fires and storefront remodeling altered many buildings, yet the district keeps much of its original character and scale.","period_of_significance":"1870-1930","architect_builder":"Unknown; buildings are the work of local builders and craftsmen, except the Nelson Hardware facade, which was fabricated in St. Louis.","architectural_style":"Vernacular and Italianate commercial architecture, in limestone ashlar","criteria":[],"status_note":"Mixed use: some buildings occupied by shops and offices, some vacant, and several under restoration at the time of the form.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:18.788201-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/81/9739/40973981/content/electronic-records/rg-079/NPS_TX/83003170.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40973981","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/williamson-county/round-rock-commercial-historic-district-83003170/"}
