It is also noted for its Georgian Revival design and high-quality exterior and interior decorative details. Its site lies within the original 1620 settlement, with potential archaeological value.","narrative":"Built in 1913-1914 at the corner of Main and Leyden Streets in Plymouth, this former post office was designed under Oscar Wenderoth, Supervising Architect for the Treasury Department. It is a Georgian Revival building of red Flemish-bond brick with Indiana limestone trim, a seven-bay portico with carved capitals, a slate roof and a wood-faced cupola. Inside, the main lobby keeps marble walls from Vermont, ceramic tile floors, plaster vaults and cast bronze details. The building reflects the federal program that produced similar post offices in small cities nationwide, though its elevations and decoration were individually designed. Its construction followed the doubling of Plymouth's population between 1870 and 1915. Alterations have been minor, mostly replacement of entry doors. After postal sorting moved elsewhere, the building was rehabilitated and now holds offices and shops. The site sits within the original 1620 settlement, so 17th-century archaeological remains may survive beneath and behind it.","period_of_significance":"1913-1914","architect_builder":"Oscar Wenderoth, Supervising Architect","architectural_style":"Georgian Revival","criteria":["A","C"],"status_note":"Only partly occupied in the late 1970s and early 1980s, then given a certified historic rehabilitation; now used for office and retail space.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:01.472699-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/30/7966/63796630/content/electronic-records/rg-079/NPS_MA/86002926.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/86002926/226cff2379-800.webp","url_1600":"https://nationalhistoricalregister.com/media/86002926/226cff2379-1600.webp","licence":"Public domain","author":"Marcbela (Marc N.
