It served as the college's dining hall and later became part of the Campus Center. Its Modern English Gothic design contributes to the group's range of architectural styles.","narrative":"Great Hall is a brick building faced with squared and coursed rubble stone on the Heidelberg College campus in Tiffin, Ohio. Built in 1925-1926 as College Commons to a Modern English Gothic design by Miller, Pullenwider, and Dowling, it has a one-story center section flanked by two-story end sections, a gabled terra cotta tile roof, and a main entrance with a Gothic arch and quoins. Before it opened, women students ate in their dormitories and men used a separate facility on Greenfield Street. Gifts from the people of Tiffin and Seneca County paid for the new dining hall. It served that purpose until Hoernemann Refectory opened in 1966, after which it was renamed Great Hall and became part of the Campus Center. A addition called The Castle was attached to the west side in 1971. The building is included among Heidelberg College resources that illustrate the college's growth since 1850.","period_of_significance":"1925-1926","architect_builder":"Miller, Pullenwider, and Dowling","architectural_style":"Modern English Gothic","criteria":[],"status_note":"Condition listed as good (interior) and very good (exterior); in use as part of the Campus Center.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.479383-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/79002777.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002777/094673e1e8-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002777/094673e1e8-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Great_Hall,_Heidelberg_University.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Great_Hall,_Heidelberg_University.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71986126","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q138673382"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/seneca-county/great-hall-79002777/"}
