It is also cited for unusual cast iron thumb latches that predate the 1840 Blakes patent and for more ornate woodwork than is typical of area farmhouses. The nomination describes it as perhaps the best local example of its type.","narrative":"Built by German settlers in Upper Bucks County, the Lewis Summers Farm sits on 15 acres of the original 98 in Tinicum Township. Its stone house, dated to about 1830 from physical and documentary evidence, is a two-pile vernacular German dwelling of red sandstone and local red shale, with a stone ell added in 1866. The 1861 frame bank barn was built by George King, who bought the farm in 1851, and the farm holds nine contributing buildings and structures in total. The complex is valued for its nearly complete set of 19th-century farm buildings in their rural setting. The house also has cast iron thumb latches with tulip designs that appear to predate the Blakes' 1840 patent, and fancier interior moldings than most area farmhouses. The farm was abandoned in the 1960s and restored from 1982, and it is regarded as a rare survivor of its type in the county.","period_of_significance":"c.1830-c.1900","architect_builder":null,"architectural_style":"Vernacular German Colonial","criteria":["C"],"status_note":"Abandoned in the 1960s, subjected to vandalism and deterioration, and restored from 1982 after the buildings with 15 acres were sold.","vacant_flag":true,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:37.625067-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/91001124.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/91001124/544892bb83-800.webp","url_1600":"https://nationalhistoricalregister.com/media/91001124/544892bb83-1600.webp","licence":"CC BY-SA 3.0","author":"PattiParker","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Lewis_Summer_Farm_2.JPG\" rel=\"noopener\">PattiParker</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:Lewis_Summer_Farm_2.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996861","wikipedia":"https://en.wikipedia.org/wiki/Lewis_Summers_Farm","wikidata":"https://www.wikidata.org/wiki/Q15242295"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bucks-county/summers-lewis-farm-91001124/"}
