The form gives a construction date of ca. 1890 in the description and ca. 1870 in the significance section.","why_significant":"The nomination presents the structures as vernacular late 19th-century Mexican-style buildings once common along the Texas border. It argues the site represents one of the last large-scale ranching efforts by people of Hispano-Mexican heritage in an Anglo-dominated region of south Texas. It also notes the site's potential to yield information on the material culture and acculturation of border Mexican-Americans.","narrative":"Two sandstone ranch houses stand near the Rio Grande, a short distance north of San Ygnacio in Zapata County, Texas. Built in the Mexican Colonial manner, they are single-story rectangular buildings with dressed sandstone walls about three-quarters of a meter thick, bonded with lime mortar and once finished with whitewashed plaster. One has a single room and the other two rooms plus a shed addition. Small openings called troneras, apparently meant for defense against bandits of the 1870s and 1880s, pierce the walls, and remnants of the original beam-and-plank flat roofs survive beneath later tin roofing. The site was listed as an example of late 19th-century border architecture and as evidence of Hispano-Mexican ranching, an industry those settlers helped establish in Texas. It is described as one of the last large-scale ranching attempts by that community in an area dominated by Anglo-Texans. The form also points to its potential for archeological research into everyday life among Mexican-Americans of the period.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":"Mexican Colonial","criteria":[],"status_note":"Condition listed as good and altered; the two-room building is used as a storage barn and the single-room building as a shop.
