The earliest section dates to the early 18th century, with a 19th-century addition and an 1884 rear ell.","why_significant":"The farm is tied to Lansing Millis, the railroad executive for whom the town is named, who assembled Oak Grove Farm as a large dairy operation after 1879. The house also shows three building phases, with First Period, Georgian and Greek Revival features. The surrounding fields, stone walls and tree-lined driveways keep the farm's historic landscape.","narrative":"Oak Grove Farm in Millis, Massachusetts, centers on a clapboard farmhouse known as the Lovell House, set on a knoll along Exchange Street within a 108-acre parcel of fields, meadows and woodland. The house grew in three phases: a five-bay early 18th-century core, a three-bay addition from the second quarter of the 19th century, and a large rear ell added in 1884. Its features include carved summer beams, Greek Revival door surrounds and a restored front porch. The property matters chiefly for its link to Lansing Millis, a railroad executive for whom the town is named. He bought the farm in 1879, built stone walls and barns, and developed a substantial dairy operation. In 1883 he moved to a nearby mansion and turned this house into a boarding house for farm workers. Stone walls, old tree-lined driveways and active fields still reflect that era. The town rehabilitated the house in 1984.","period_of_significance":null,"architect_builder":null,"architectural_style":"Mid-19th Century: Greek Revival; Colonial: First Period, Georgian","criteria":[],"status_note":"Vacant and deteriorated for several years before the town took it over and rehabilitated it in 1984; the rear ell was made into an apartment and surrounding fields are still farmed.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:10:51.583414-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/20/7964/63796420/content/electronic-records/rg-079/NPS_MA/11000247.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/11000247/0160f314c8-800.webp","url_1600":"https://nationalhistoricalregister.com/media/11000247/0160f314c8-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:MillisMA_OakGroveFarm.jpg\" rel=\"noopener\">User:Magicpiano</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:MillisMA_OakGroveFarm.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63796420","wikipedia":"https://en.wikipedia.org/wiki/Oak_Grove_Farm","wikidata":"https://www.wikidata.org/wiki/Q16896029"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/norfolk-county/oak-grove-farm-11000247/"}
