The main block was built in the mid-19th century for John F. Cotting, with a rear ell added near the end of the 19th century.","why_significant":"The nomination argues the house is an intact, well-preserved and finely detailed temple-front Greek Revival residence. It is also tied to the Cotting family, who were leaders in Marlborough's commercial, civic and social life during the 19th century. It is cited under Criteria A, B and C.","narrative":"Facing the town common on Main Street in Marlborough's historic center, this two-and-a-half-story house is a temple-front example of Greek Revival design. Its gable-ended facade carries a pedimented portico with four two-story Doric columns, and the clapboarded walls have windows capped by molded pediments. A lower two-story ell was added at the rear near the end of the 19th century. The interior has changed little, retaining a tin ceiling in the front hall and window moldings that echo the exterior. The house was built in 1851 for John F. Cotting, who served as selectman and postmaster. His family included a physician who arrived in 1799 and a tavern builder whose inn stood next door until 1948. The Cottings held the house until about 1900. It is listed as a well-preserved example of its style and for its link to a prominent local family. It has since been rehabilitated for office use.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":"Greek Revival (temple front)","criteria":["A","B","C"],"status_note":"Recently renovated, with the interior converted to office use; the rehabilitation was certified in 1982 as meeting the Secretary of the Interior's Standards for Rehabilitation.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:57.735007-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/66/7956/63795666/content/electronic-records/rg-079/NPS_MA/84002556.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/84002556/b51fbc781a-800.webp","url_1600":"https://nationalhistoricalregister.com/media/84002556/b51fbc781a-1600.webp","licence":"CC BY-SA 3.0","author":"Tim Pierce","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:John_Cotting_House.jpg\" rel=\"noopener\">Tim Pierce</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:John_Cotting_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63795666","wikipedia":"https://en.wikipedia.org/wiki/John_Cotting_House","wikidata":"https://www.wikidata.org/wiki/Q6227240"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/cotting-john-house-84002556/"}
