It represents a large group of transitional structures in which decorative embellishment of the exposed frame becomes minimal and finishes such as vertical feather-edged sheathing appear. It is eligible under Criterion C for its distinctive form and construction.","narrative":"This house at 93 West Main Street in Georgetown, Massachusetts, is a 2 1/2-story, five-bay, one-room-deep frame dwelling with a clapboarded exterior, symmetrical windows, a central chimney and a pedimented doorway. It probably began around 1725 as a single-cell structure made up of the right-hand rooms and chimney bay, and was likely built by Isaac Adams after he bought the property in 1716. A wing was added around 1800, and a rear addition followed in the 1970s. Inside, the right-hand rooms keep a chamfered hardwood summer beam with taper stops, deep feather-edged vertical sheathing, and a possibly original cellar staircase. Later features include a Second Period staircase, raised-field paneling and a delicate Federal stair in the wing. In the late 18th century it was home to Captain Benjamin Adams, a Revolutionary War officer. It was listed for its late First Period construction, which shows the shift toward minimal frame decoration and newer finishes.","period_of_significance":null,"architect_builder":"Architect unknown; probably built by Isaac Adams","architectural_style":"1st Period core with Federal vernacular exterior","criteria":["C"],"status_note":"Condition is described as good; the building is in present use as a residence.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:03.420533-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/42/7900/63790042/content/electronic-records/rg-079/NPS_MA/90000211.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/90000211/c40745165f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/90000211/c40745165f-1600.webp","licence":"CC BY-SA 3.0","author":"Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:GeorgetownMA_AdamsClarkeHouse.jpg\" rel=\"noopener\">Magicpiano</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:GeorgetownMA_AdamsClarkeHouse.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63790042","wikipedia":"https://en.wikipedia.org/wiki/Adams%E2%80%93Clarke_House","wikidata":"https://www.wikidata.org/wiki/Q14715380"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/essex-county/adams-clarke-house-90000211/"}
