This amendment revises the construction date from about 1636 to about 1720.","why_significant":"The house is significant under Criterion C for architecture, as an example of Colonial vernacular building. Tree-ring dating, archaeological work and architectural study by Colonial Williamsburg staff show that it was built around 1720, not in the 17th century as first thought. The period of significance is amended to cover both the 17th and 18th centuries.","narrative":"Adam Thoroughgood House is a brick dwelling on Parrish Road in Virginia Beach, now used as a museum. It measures about 45 by 22 feet and has a steep gabled roof, two large end chimneys and a center-passage plan with two rooms. Earlier scholars dated it to about 1636, but later studies changed that view. A tree-ring report, an archaeological survey and architectural research by Colonial Williamsburg Foundation staff point to construction around 1720. Features such as the center passage, the tilted false plate and the brickwork fit early 18th-century Chesapeake building practice. The archaeology found no evidence of 17th-century use of the site. A 1957 restoration removed dormers, reduced window sizes and altered the roof covering, though much early fabric survives. The house is recognized for architecture, and its period of significance now spans the 17th and 18th centuries.","period_of_significance":"17th century and 18th century","architect_builder":null,"architectural_style":"COLONIAL/Vernacular","criteria":["C"],"status_note":"Currently used as a museum; it was restored in 1957 and opened to the public that year.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:56.606681-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/77/6839/41683977/content/electronic-records/rg-079/NPS_VA/66000921.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/66000921/255d7340d0-800.webp","url_1600":"https://nationalhistoricalregister.com/media/66000921/255d7340d0-1600.webp","licence":"CC BY-SA 4.0","author":"PumpkinSky","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Adam_Thoroughgood_House_-_South_LR.jpg\" rel=\"noopener\">PumpkinSky</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:Adam_Thoroughgood_House_-_South_LR.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41683977","wikipedia":"https://en.wikipedia.org/wiki/Adam_Thoroughgood_House","wikidata":"https://www.wikidata.org/wiki/Q4679897"},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/virginia-beach/thoroughgood-house-66000921/"}
