The farmhouse was built around 1750 with later additions, and the mill was purportedly built around 1728 by George Boone.","why_significant":"The nomination argues that the complex is an excellent example of an 18th century farm-mill complex whose buildings largely date from the mid or late 18th century and preserve the spatial layout of an early farm. It highlights the Georgian facade and the surviving interior paneling and hardware of the farmhouse as examples of colonial craftsmanship. It also links the property to the Boone family, who held the tract until 1790.","narrative":"Mill Tract Farm is a group of 18th century stone buildings in Berks County, Pennsylvania, centred on a farmhouse, a gristmill and a barn. The main house was built around 1750 in a five-bay Georgian form, with a six-panel door, a rectangular transom, and a gable roof. Additions followed in 1790 and between 1790 and 1820. The mill, a stuccoed stone building facing Limekiln Creek, is said to date from about 1728 and is attributed to George Boone, grandfather of Daniel Boone. Its exterior is largely intact, although it retains little of its original machinery. The farmhouse interior keeps wide-board floors, plastered walls, chair rails, and fireplace walls with fine Georgian paneling and original wrought-iron hardware. The surviving stone barn, dating from the late 18th century, adds to the group. The complex is regarded as an excellent example of 18th century farm and mill architecture.","period_of_significance":"1728-1790","architect_builder":"George Boone (purportedly built the mill); James Boone (built the Georgian section of the farmhouse)","architectural_style":"Georgian","criteria":[],"status_note":"The farm and mill complex is in a good state of preservation and is being well maintained by the property owner.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.469493-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/77001124.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/77001124/aa33b6d4c3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/77001124/aa33b6d4c3-1600.webp","licence":"Public domain","author":"Cervin Robinson, Photographer","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Mill_Tract_Farm_September_1958.jpg\" rel=\"noopener\">Cervin Robinson, Photographer</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Mill_Tract_Farm_September_1958.jpg"},"district":{"nrhp_refnum":"83002218","name":"Oley Township Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/oley-township-historic-district-83002218/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998281","wikipedia":"https://en.wikipedia.org/wiki/Mill_Tract_Farm","wikidata":"https://www.wikidata.org/wiki/Q6858431"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/berks-county/mill-tract-farm-77001124/"}
