Boston architect William Pitt Wentworth designed the first buildings in the Queen Anne style, using red brick, slate roofs and corbelled cornices. Small and medium-sized wards face a rectangular central green that holds the chapel, kitchen and dining halls, giving the campus the look of a college or a New England town common. It was the state's first facility built for long-term chronic patients and the first insane hospital laid out on the cottage plan. Later buildings from the early twentieth century, by firms such as Park & Kendall and Shepley, Rutan & Coolidge, add Classical Revival and Craftsman designs. Farmland, woodland, a cemetery and a pre-existing farmhouse of about 1840 complete the grounds. The campus was recognized for its architecture and its role in the history of mental health care, with a period of significance from 1892 to 1940.","period_of_significance":"1892-1940","architect_builder":"William Pitt Wentworth; Park & Kendall; Shepley, Rutan & Coolidge","architectural_style":"Queen Anne (original buildings), with Greek Revival, Colonial Revival, Beaux-Arts, Classical Revival and Craftsman elements","criteria":["A","C"],"status_note":"Several buildings are described as vacant and boarded; landscapes are well maintained and the campus retains a high degree of integrity.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:03.506147-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/80/7924/63792480/content/electronic-records/rg-079/NPS_MA/93001481.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/93001481/a6ba26cd2b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/93001481/a6ba26cd2b-1600.webp","licence":"CC BY-SA 3.0","author":"Ghostfacesouthshore","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Medfield_State_Hospital.jpg\" rel=\"noopener\">Ghostfacesouthshore</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:Medfield_State_Hospital.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63792480","wikipedia":"https://en.wikipedia.org/wiki/Medfield_State_Hospital","wikidata":"https://www.wikidata.org/wiki/Q6805293"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/norfolk-county/medfield-state-hospital-93001481/"}
