It includes the stone Isaac Garrett farmhouse begun c. 1755, a double-decker stone barn, a stuccoed Second Empire house built in 1872, and a stone springhouse.","why_significant":"The nomination argues the farmstead is a representative example of local farm architecture in Chester County from the mid-18th to the early 20th century. It shows how a Penn Plan core was enlarged over time, how the original barn was replaced by a larger double-decker barn, and how a prosperous family built a stylish Second Empire house in 1872. The buildings are described as highly intact inside and out.","narrative":"Located in Willistown Township, Chester County, the Garrett Farmstead is a cluster of farm buildings set in open fields and woodland. The oldest part is the stone Isaac Garrett farmhouse, a Penn Plan core that the nomination dates to about 1755, later enlarged with a stone section around 1826 and a kitchen wing around 1937. A double-decker stone barn was built around 1850, when the earlier barn was converted into a tenant house. In 1872 Amos and Anna Garrett built a stuccoed Second Empire house nearby, and its date stone reads \"A & AM Garrett 1872.\" The farmstead is regarded as a representative example of Chester County farm building from the mid-eighteenth through the early twentieth century. Its houses, barn and springhouse show how farm buildings were added to and altered as crop output grew and as the land later passed to owners who did not farm it commercially. The buildings retain much of their original interior and exterior fabric.","period_of_significance":"1755 - 1937","architect_builder":null,"architectural_style":"Colonial; Second Empire","criteria":["C"],"status_note":"The land is no longer farmed, and the Amos and Anna Garrett house has been owned by the Walls since 1981.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:36.23175-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/03000076.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/03000076/f95915d74b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/03000076/f95915d74b-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Garrett_Farmhouse.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Garrett_Farmhouse.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996759","wikipedia":"https://en.wikipedia.org/wiki/Garrett_Farmstead","wikidata":"https://www.wikidata.org/wiki/Q115803102"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/garrett-farmstead-03000076/"}
