Together with the old Vermilion mill, it represents the history of milling in Vermilion from the mid-19th century into the 20th century. Another building from the complex was disassembled and moved here from Mill Hollow.","narrative":"Located at the southeast corner of Exchange and Mill streets in Vermilion, Ohio, this three-story mill dates from about 1900. It looks much like a barn, though its lower portion is built of masonry. The structure has heavy timber wall construction on a clay tile foundation, vertical siding, and a gambrel roof covered with asphalt shingles. The interior is divided into several levels, and other buildings attached to it were once part of the mill operation. The mill sat along the railroad tracks at the end of Exchange Street, a street otherwise lined with homes. One building from the complex was originally at Mill Hollow before it was taken apart and moved to this site. The property was recognized because, together with the old Vermilion mill, it helps show how milling shaped Vermilion from the mid-19th century into the 20th century. The inventory describes the mill as long abandoned, with storage as its present use, an exterior in good condition and an interior in fair condition.","period_of_significance":null,"architect_builder":null,"architectural_style":"Vernacular","criteria":[],"status_note":"Described as long since abandoned and currently used for storage; interior condition fair, exterior good.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.545592-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/79003929.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71984932","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/erie-county/old-mill-79003929/"}
