It was moved from Fayette Street to its present site in 1856.","why_significant":"The nomination calls it one of the city's finest three-bay side-hall Greek Revival houses, in remarkably intact condition. It is the only Cambridge Greek Revival example to keep its wrap-around Ionic porch and octagonal cupola intact. It was also one of the first houses built in the area, which makes it important to the development of Mid Cambridge.","narrative":"Built in 1843, this clapboard house at 125 Antrim Street in Cambridge is a three-bay, side-hall Greek Revival dwelling. Its most notable features are a wrap-around porch with Ionic capitals on three columns, large corner pilasters with leaf-molded capitals, and an octagonal cupola. The house originally stood on Fayette Street and was moved to its present site in 1856. It was built for Isaac Fay, who later served as a city alderman and supported the Cambridge Hospital. The nomination describes it as one of the city's finest examples of its type, in remarkably intact condition, and the only Greek Revival house in Cambridge that still retains both the porch and the cupola. It also marks the early development of the Mid Cambridge area. Land south of Cambridge Street, held by real estate speculators, stayed unbuilt until the 1840s, when parallel streets were laid out and lots sold quickly. This was among the first houses there. It is listed for its architectural significance.","period_of_significance":null,"architect_builder":null,"architectural_style":"Greek Revival","criteria":["C"],"status_note":"Present use is residential; the form says the house is unaltered but was moved in 1856.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:57.110331-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/79/7905/63790579/content/electronic-records/rg-079/NPS_MA/83000799.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/83000799/e9e8fa5573-800.webp","url_1600":"https://nationalhistoricalregister.com/media/83000799/e9e8fa5573-1600.webp","licence":"CC BY-SA 3.0","author":"Tim Pierce","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Issac_Fay_House_detail.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:Issac_Fay_House_detail.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63790579","wikipedia":"https://en.wikipedia.org/wiki/Isaac_Fay_House","wikidata":"https://www.wikidata.org/wiki/Q6076300"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/fay-issac-house-83000799/"}
