It is also architecturally notable for its rough stone construction and the pegged-timber truss in the attic that permits an open interior.","narrative":"Built about 1839-40 by local people on the Daniel H. Knoop farm, this rough stone building in Casstown, Ohio, served the local Lutheran congregation until a new brick church was dedicated next door in 1868. It was then converted to a dwelling, with remodeling described as sensitive to the original features. The walls are 20 inches thick, and the interior keeps its open church space, supported by pegged chestnut and oak trusses in the attic. The same truss design appears in the 1813 John Minor Dye Stone House nearby. The church is tied to the growth of Pennsylvania German Lutheran congregations in the Miami Valley and the formation of a Western District of the Joint Synod of Lutherans of Ohio. The Knoop family, early settlers of Miami County, helped found the congregation. The building is valued for that religious history and for its unusual stone construction and structural framing.","period_of_significance":"1800-1899 (specific dates 1839-40)","architect_builder":null,"architectural_style":null,"criteria":["A","C"],"status_note":"Occupied and used as a private residence since the congregation moved to a new brick church in 1867-68; the form says it has changed little in about 115 years.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:14.195871-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/84003783.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/84003783/914188fc16-800.webp","url_1600":"https://nationalhistoricalregister.com/media/84003783/914188fc16-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Casstown_Lutheran_Stone_Church_from_southwest.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Casstown_Lutheran_Stone_Church_from_southwest.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71990307","wikipedia":"https://en.wikipedia.org/wiki/Casstown_Lutheran_Stone_Church","wikidata":"https://www.wikidata.org/wiki/Q5049515"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/miami-county/casstown-lutheran-stone-church-84003783/"}
