It was an outbuilding on Daniel Webster's \"Green Harbor\" estate and was moved to its present site in 1966.","why_significant":"The building is the only surviving structure of Daniel Webster's Green Harbor estate, where he kept his natural history library and worked as a lawyer. Webster was a statesman, orator and lawyer who championed the Union, and Green Harbor was his true home. The nomination also notes his major Supreme Court cases and his role as Secretary of State.","narrative":"This small yellow clapboard building in Marshfield, Massachusetts, served as the law office and natural history library of Daniel Webster. It stood on his Green Harbor estate, which he began assembling in 1832 with the purchase of a 160-acre property and later expanded by another 1,200 acres before his death in 1852. The main house burned in 1878, leaving the office as the only surviving structure from the estate. In 1966 the Marshfield Historical Commission moved it about half a mile from its original site to land that was once part of the Webster property, restored it and opened it to the public. Inside are Webster memorabilia and several pieces of his furniture. Webster was a lawyer, orator and statesman known for defending the Union, arguing the Dartmouth College case, and serving as Secretary of State. The building preserves his connection to Marshfield, which he treated as his true home.","period_of_significance":"1832-1852","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Restored and open to the public as a museum holding Webster memorabilia and some furniture from his home; condition listed as good.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:55.052516-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/15/7938/63793815/content/electronic-records/rg-079/NPS_MA/74002053_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/74002053/b427209533-800.webp","url_1600":"https://nationalhistoricalregister.com/media/74002053/b427209533-1600.webp","licence":"Public domain","author":"National Park Service photographer","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Daniel_Webster_Law_Office,_Marchfield_(Plymouth_County,_Massachusetts).jpg\" rel=\"noopener\">National Park Service photographer</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Daniel_Webster_Law_Office,_Marchfield_(Plymouth_County,_Massachusetts).jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63793815","wikipedia":"https://en.wikipedia.org/wiki/Daniel_Webster_Law_Office","wikidata":"https://www.wikidata.org/wiki/Q5219056"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/plymouth-county/webster-daniel-law-office-and-library-74002053/"}
