Its 71 buildings are mostly large houses, with garages or barns behind, set on broad lawns under mature trees. The oldest is the Solomon Boltwood House of 1751, and the district includes Greek Revival, Gothic Revival, Italianate and Second Empire houses, along with later Colonial Revival ones. Most construction took place between 1870 and 1915, when local factories, businesses, Amherst College and the Massachusetts Agricultural College brought prosperity. Merchants, professionals and some professors built here, giving the area its nickname, Millionaire's Row. The real estate firm Westcott, Westcott and Stockbridge subdivided land into more than thirty building lots with deed restrictions that required a consistent streetscape, an early example of neighborhood planning in Amherst. The district was listed for its architecture, planning and social history, with a period of significance from 1751 to 1930.","period_of_significance":"1751-1930","architect_builder":"Putnam, Karl","architectural_style":"Greek Revival, Italianate, Colonial Revival (also Federal, Gothic Revival and Second Empire examples)","criteria":["A","C"],"status_note":"Residential district; houses with rear garages or barns remain in single-dwelling use. 52 contributing and 19 noncontributing buildings.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:04.840466-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/47/7954/63795447/content/electronic-records/rg-079/NPS_MA/93000008.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/93000008/8b2a20b35e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/93000008/8b2a20b35e-1600.webp","licence":"CC BY 3.0","author":"John Phelan","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:A_house_on_Lincoln_Ave,_Amherst_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:A_house_on_Lincoln_Ave,_Amherst_MA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63795447","wikipedia":"https://en.wikipedia.org/wiki/Lincoln%E2%80%93Sunset_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q6550426"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/hampshire-county/lincoln-sunset-historic-district-93000008/"}
