The property also includes a section of the first Spanish acequia (irrigation canal), dating to about 1718.","why_significant":"The nomination argues the house is a rare surviving example of the two-story stone I-plan dwellings built by German immigrants in San Antonio, and one of few remaining historic buildings in the Irish Flat neighborhood. The adjoining open section of the Acequia Madre branch is one of four surviving open portions in the central city. It is listed under Criterion C for architecture at the local level.","narrative":"Built about 1882 at 121 Starr Street, east of downtown San Antonio, this two-story house was constructed by German stonemason Johann Heidgen to hold his large family. Its ground floor uses rubble limestone and its upper floor cut caliche block, with walls averaging 16 inches thick and a side-gabled standing seam metal roof extending over an upper gallery. The west wall sits directly on the curb of a branch of the Acequia Madre, the Spanish irrigation canal begun around 1718 to supply the Alamo mission; this open stretch, about four and a half feet wide, is one of four surviving in the central city. The house is described as a rare surviving example of a once-common German vernacular type. It was restored in 1971 and is now a professional office. The Heidgen family was also closely involved in building and sustaining St. Joseph's Catholic Church. The property is listed for its architecture at the local level.","period_of_significance":"1882","architect_builder":"Heidgen, Johann","architectural_style":"OTHER/I-plan, canal (acequia); vernacular German house","criteria":["C"],"status_note":"Currently used as a professional office (a lawyer's office); restored in 1971 for the Alamo Council of Camp Fire Girls.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:23.720925-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/23/9711/40971123/content/electronic-records/rg-079/NPS_TX/04000591.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/04000591/0e706c1243-800.webp","url_1600":"https://nationalhistoricalregister.com/media/04000591/0e706c1243-1600.webp","licence":"CC BY-SA 3.0","author":"25or6to4","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Johann_and_Anna_Heidgen_House,_San_Antonio,_Texas.jpg\" rel=\"noopener\">25or6to4</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Johann_and_Anna_Heidgen_House,_San_Antonio,_Texas.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40971123","wikipedia":"https://en.wikipedia.org/wiki/Johann_and_Anna_Heidgen_House","wikidata":"https://www.wikidata.org/wiki/Q6216320"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/bexar-county/heidgen-johann-and-anna-house-04000591/"}
