Boutwell and now used as a museum by the Groton Historical Society.","why_significant":"The house was the home of Gov. George S. Boutwell, who served as Massachusetts governor, U.S. Congressman, Secretary of the Treasury under President Grant, and U.S. Senator. It retains a largely unaltered mid-19th-century interior, including its kitchen chimney with bake oven and set kettles. The form also notes a high potential for historic archaeological resources on the lot.","narrative":"Built in 1851 on Main Street in Groton's town center, this 2½-story clapboard house blends Greek Revival and Italianate design. Its features include quoined corners, a deep bracketed cornice, a canopy over the center entry, and a rear wing expanded in the late 19th century. Inside, a broad center hall with a curving staircase, marble mantels, paneled blinds and a preserved brick kitchen chimney with bake oven survive largely unchanged since the owner's death in 1905. George S. Boutwell built the house in the year he became Massachusetts governor. He later served in Congress, helped write the 14th and 15th amendments, managed the impeachment of President Andrew Johnson, and became Secretary of the Treasury under Ulysses S. Grant, who visited the house in 1869. The property also includes a granite retaining wall, hitching post and mounting block, and a 1960s storage building. The Groton Historical Society now operates it as a museum.","period_of_significance":null,"architect_builder":null,"architectural_style":"Mid-19th Century: Greek Revival; Mid-19th Century: Italianate","criteria":[],"status_note":"Used as a museum by the Groton Historical Society, with two tenant apartments in the rear wing created in 1939-40.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:04.278518-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/20/7958/63795820/content/electronic-records/rg-079/NPS_MA/04001431.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/04001431/9d97089d2d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/04001431/9d97089d2d-1600.webp","licence":"CC BY 3.0","author":"John Phelan","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Gov._George_S._Boutwell_House,_Groton_MA.jpg\" rel=\"noopener\">John Phelan</a>, <a href=\"https://creativecommons.org/licenses/by/3.0\" rel=\"license noopener\">CC BY 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Gov._George_S._Boutwell_House,_Groton_MA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63795820","wikipedia":"https://en.wikipedia.org/wiki/Gov._George_S._Boutwell_House","wikidata":"https://www.wikidata.org/wiki/Q5588521"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/boutwell-gov-george-s-house-04001431/"}
