Its locally procured fieldstone exterior is a rare feature among post offices of the period and reflects the local Dutch Colonial building tradition. It also holds a well-preserved 1937 mural series by Charles Rosen, painted under the Treasury Relief Arts Project.","narrative":"Fieldstone gives this post office at 369 Main Street in Beacon, New York, a look unusual for its era. Built between 1935 and 1937 with a $110,000 federal authorization, it is a one-story, five-bay Colonial Revival building with a slate gable roof, cupola, pedimented front and a cast-pewter eagle. Gilbert Stanley Underwood, a consulting architect who worked mostly in the western states, designed it, and it was his only post office in New York. Most post offices of the time were red brick, but this one uses local fieldstone, echoing the Dutch Colonial building tradition of the area. Inside, the lobby has marble floors, a marble dado, and arched alcoves on marble pilasters. Charles Rosen painted the mural series in 1937 under the Treasury Relief Arts Project, showing county maps of the Hudson Valley and local scenes. The building is valued as an intact Depression-era federal work with notable art.","period_of_significance":"1935-1937","architect_builder":"Gilbert Stanley Underwood, Consulting Architect","architectural_style":"Colonial Revival","criteria":[],"status_note":"Described as well maintained and retaining a high degree of integrity inside and outside; still used as the post office, with some windows replaced.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:44.808507-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/88002456.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/88002456/a7c5962ed7-800.webp","url_1600":"https://nationalhistoricalregister.com/media/88002456/a7c5962ed7-1600.webp","licence":"CC BY-SA 4.0","author":"AlexiusHoratius","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Beacon_NY_Post_Office_5.jpg\" rel=\"noopener\">AlexiusHoratius</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:Beacon_NY_Post_Office_5.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75312640","wikipedia":"https://en.wikipedia.org/wiki/United_States_Post_Office_(Beacon,_New_York)","wikidata":"https://www.wikidata.org/wiki/Q14707550"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/dutchess-county/us-post-office-beacon-88002456/"}
