It comprises a brick farmhouse begun around 1833, with outbuildings including a large Pennsylvania barn of 1839, on a rise above Crooked Creek.","why_significant":"The nomination argues the farm is significant under Criterion A for its association with the evolution of agriculture in Huntingdon County. It is presented as illustrating changing farming practices and market orientation from the 1830s through the mid-twentieth century, and as meeting or exceeding township averages over time. The period of significance runs from 1833 to 1959.","narrative":"Set on a rise above Crooked Creek in the limestone Hartslog Valley, the Robb Farm is a 179-acre working farmstead whose core is a brick farmhouse begun around 1833 in the 3/5 Georgian form. William Robb, an Irish-born settler, commissioned the house after purchasing the property in 1833, and bricks were cast from creek-side clay and fired on site. The farmhouse was enlarged around 1864 by his son Livingston Robb, who reoriented the house toward the improved road and added Italianate touches. The complex includes a Pennsylvania barn dated 1839, a springhouse, a wagon shed, a milk house and a garage, eleven contributing buildings in all. The farm is regarded as a clear record of agricultural change in Huntingdon County, moving from grain and livestock to diversified market farming as canals and railroads reached the region. Its layout of fields, woodlot and house yard still reflects the 1845 subdivision. The period of significance runs from 1833 to 1959.","period_of_significance":"1833-1959","architect_builder":null,"architectural_style":"Colonial / Georgian; Early Republic / Federal; Late Victorian / Italianate","criteria":["A"],"status_note":"The house is described as having been re-pointed and sandblasted around 1985 and having a forced hot air furnace added about 1985; the document does not state a current use.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:10:27.590041-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/11000202.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/11000202/599db9adb6-800.webp","url_1600":"https://nationalhistoricalregister.com/media/11000202/599db9adb6-1600.webp","licence":"CC BY-SA 3.0","author":"Generic1139","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Robb_Farm_house.jpg\" rel=\"noopener\">Generic1139</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:Robb_Farm_house.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998493","wikipedia":"https://en.wikipedia.org/wiki/Robb_Farm","wikidata":"https://www.wikidata.org/wiki/Q7340772"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/huntingdon-county/robb-farm-11000202/"}
