It is also valued as an example of Colonial architecture and is the last of the many country estates of its period remaining in Jamaica Plain.","narrative":"Built in 1760 for Joshua Loring, a privateer and Royal Navy officer who earned the title of Commodore, this nearly square, two-story clapboard mansion sits on a low rise at 12 South Street in Jamaica Plain. It has a granite foundation, a hipped roof with a balustrade, Doric-columned entrance porches, and a carriage house ell added around 1811. It is the last of the many country estates of its era left in the neighborhood. Loring, a Loyalist, fled Boston with the British in March 1776. In June 1775 General Nathanael Greene made the house his headquarters, and it was appointed a hospital for the camp in Roxbury, making it one of the first American military hospitals. After confiscation in 1779 it was sold, and Anne Doane bought it in 1784. The Greenough family owned it until 1924. Later changes include 19th century alterations to the hall and north entrance, and Federal period updates to the windows and balustrade.","period_of_significance":"1760; 1775-76 (18th century)","architect_builder":null,"architectural_style":"Colonial, with Federal period alterations","criteria":[],"status_note":"Condition is listed as good, altered, on its original site; used as a museum and club.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:53.117912-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/61/7969/63796961/content/electronic-records/rg-079/NPS_MA/72000544.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/72000544/a9e05972c8-800.webp","url_1600":"https://nationalhistoricalregister.com/media/72000544/a9e05972c8-1600.webp","licence":"Public domain","author":"Biruitorul (talk)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Loring-Greenough.JPG\" rel=\"noopener\">Biruitorul (talk)</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Loring-Greenough.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63796961","wikipedia":"https://en.wikipedia.org/wiki/Loring%E2%80%93Greenough_House","wikidata":"https://www.wikidata.org/wiki/Q14715676"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/suffolk-county/loring-greenough-house-72000544/"}
