The house remains almost completely intact from his residency. It is now a composers' retreat and creative center for American music.","narrative":"Set on a rock ledge in Cortlandt Manor, this one-story, L-shaped frame house was built in the mid-1940s and later became the home of composer Aaron Copland. He bought the property, known as Rock Hill, in 1960 and lived and worked there until his death in 1990. The house has a stone foundation, green-painted clapboard walls, vaulted asphalt roofs and many large picture windows that connect the rooms to the surrounding woodland. Inside are six main rooms, including a glass-walled studio with his grand piano and desk. A detached garage with an apartment Copland added sits nearby. The grounds cover 2.5 acres of terraced gardens. The property was listed for its association with Copland, whose works include Appalachian Spring, Rodeo and Fanfare for the Common Man. Little has been altered since his time, and the house now serves as a retreat where selected composers stay and work, and as a center for American music.","period_of_significance":"1960-90","architect_builder":null,"architectural_style":"Modern Movement: Wrightian","criteria":["B"],"status_note":"Used as a composers' retreat and music facility (Copland House); described as almost completely intact from Copland's residency, with interior restored.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:40.066916-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/03000245.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/03000245/a262f3e48f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/03000245/a262f3e48f-1600.webp","licence":"CC BY-SA 3.0","author":"Daniel Case","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Aaron_Copland_House,_Cortlandt_Manor,_NY.jpg\" rel=\"noopener\">Daniel Case</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:Aaron_Copland_House,_Cortlandt_Manor,_NY.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75322991","wikipedia":"https://en.wikipedia.org/wiki/Aaron_Copland_House","wikidata":"https://www.wikidata.org/wiki/Q2613021"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/westchester-county/copland-aaron-house-03000245/"}
