It has a central chimney and a later lean-to.","why_significant":"The form argues the house keeps its First Period frame, floor plan and finish, and shows the growth from a single-cell to a double-cell plan within the First Period. It retains rare evidence of 17th-century facade gables, two kinds of original shadow-molded sheathing, and an intact principal rafter/common rafter roof. It was also restored in 1907 by a local historical society for use as a house museum, an early example of preservation.","narrative":"At 40 Shirley Street in Winthrop, Massachusetts, stands a 2 1/2 story timber-framed house with a steep roof, five bays across and one room deep, with a lean-to added in the 18th century. It began as a single-room-plan building and was soon widened with a second set of rooms to the east. The first survey dated it to about 1638-1650, but tree-ring testing in 2001 pointed to 1675 for the west section and 1696 for the east. Inside, it keeps chamfered beams, jowled posts, original shadow-molded wall sheathing and a principal rafter roof, while cuts in the roof sheathing show where gables once rose on the facade. The site was granted to Captain William Pierce in 1638 and later passed to Deane Winthrop, youngest son of Governor John Winthrop. A local historical association bought and restored the house in 1907 for use as a house museum, an early preservation effort in New England.","period_of_significance":null,"architect_builder":null,"architectural_style":"First Period","criteria":["C"],"status_note":"Recorded in good condition in 1986 and in residential use; a late 20th-century tool shed stands on the lot.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:03.958188-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/71/7907/63790771/content/electronic-records/rg-079/NPS_MA/90000162.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/90000162/04dab20998-800.webp","url_1600":"https://nationalhistoricalregister.com/media/90000162/04dab20998-1600.webp","licence":"CC BY-SA 3.0","author":"Jameslwoodward","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Deane_Winthrop_House_Winthrop_MA_02.jpg\" rel=\"noopener\">Jameslwoodward</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:Deane_Winthrop_House_Winthrop_MA_02.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63790771","wikipedia":"https://en.wikipedia.org/wiki/Deane_Winthrop_House","wikidata":"https://www.wikidata.org/wiki/Q5246720"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/suffolk-county/winthrop-deane-house-90000162/"}
