It embodies first-period construction expanded by later owners. It was long held by the Wheeler family, one of Concord's earliest and largest families, and later served as a tavern run by William Parkman, who carried the alarm of April 19, 1775.","narrative":"Parkman Tavern is a two-and-a-half-story, five-bay clapboard house at the corner of Sudbury and Powder Mill Roads in Concord, next to a small pond. Its core is believed to have been built in 1659 by George Wheeler for his son William. Seventeenth century features survive inside, including feather-edged sheathing, chamfered beams, early plaster and traces of casement windows. The house was remodeled in 1770 and again around 1820, when the facade took on its Greek Revival appearance with sidelights and a shallow pediment over the entrance. The Wheeler family owned it for most of its history. William Parkman, a Boston merchant, bought it in 1770 and operated it as a tavern on the South Road, a route used by teamsters. Parkman was one of the messengers sent to warn neighboring towns on April 19, 1775. Later Wheeler Captain Artemas Wheeler, a gunsmith, patented a revolving-cylinder gun in 1818.","period_of_significance":null,"architect_builder":"George Wheeler","architectural_style":"First period (17th century) construction with Greek Revival remodeling of the facade","criteria":[],"status_note":"Occupied private residence; the form notes that the current owners restored the 17th century sheathing.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:53.40087-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/27/7959/63795927/content/electronic-records/rg-079/NPS_MA/79000358.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79000358/6beb52bc10-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79000358/6beb52bc10-1600.webp","licence":"CC BY 3.0","author":"John Phelan","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Parkman_Tavern,_Concord_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:Parkman_Tavern,_Concord_MA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63795927","wikipedia":"https://en.wikipedia.org/wiki/Parkman_Tavern","wikidata":"https://www.wikidata.org/wiki/Q7138605"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/parkman-tavern-79000358/"}
