Vernon Street in East Somerville, Massachusetts, built about 1845-1850 with clapboard walls and a ca. 1930 garage.","why_significant":"The house is a fine example of a one and one-half story Greek Revival cottage and keeps its integrity of location, design, materials, workmanship and association. It represents the mid-19th century residential development of East Somerville, the only part of Somerville that still has a concentration of Greek Revival cottages from the 1840s and 1850s. It is also the only house of its size among the two and one-half story side hall cottages across the street.","narrative":"This one and one-half story Greek Revival cottage at 29 Mt. Vernon Street in East Somerville dates to about 1845-1850. It is clad in clapboard and has a garage added around 1930. The street was platted in 1845 and soon filled with Greek Revival cottages, drawing Boston businessmen and artisans who valued the nearby Charlestown and the Boston and Maine Railroad. The house has a temple-form gable end with wide eaves and a full entablature, carried by a full-width Ionic porch. Full-length windows with high-profile lintels and an elaborate entrance framed by decorative panels add to its Greek Revival character. It is the only house of its size among the two and one-half story side hall cottages on the opposite side of the street. East Somerville is the only part of the city that still has a concentration of these cottages, and the house keeps its original location, design, materials and workmanship, in good condition and with no major alterations. It was recognized for its architecture at the local level.","period_of_significance":null,"architect_builder":null,"architectural_style":"Greek Revival","criteria":["C"],"status_note":"Residential use, in good condition, with no major alterations and not moved.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:01.492747-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/56/7921/63792156/content/electronic-records/rg-079/NPS_MA/89001302.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/89001302/964f05ee9d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/89001302/964f05ee9d-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:SomervilleMA_HouseAt29MountVernonStreet.jpg\" rel=\"noopener\">User:Magicpiano</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:SomervilleMA_HouseAt29MountVernonStreet.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63792156","wikipedia":"https://en.wikipedia.org/wiki/House_at_29_Mt._Vernon_Street","wikidata":"https://www.wikidata.org/wiki/Q5914203"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/house-at-29-mt-vernon-street-89001302/"}
