It has a heavy timber frame, vertical wood siding, a sandstone foundation, a gable roof with asphalt shingles, and original four-over-four windows. Its overall shape recalls Greek Revival buildings, though it carries no ornament that would identify it as such. The mill began as a water-powered operation at Mill Hollow in the early nineteenth century. It was later taken apart and moved to its present site beside the railroad. In 1909 H.H. Berk and son bought it and made \"White Swan Flour\" there until 1916. The building was listed as a reminder of Vermilion's part in exporting grain. At the time of the survey it was in fair condition, looked dilapidated, and served as warehouse storage.","period_of_significance":null,"architect_builder":null,"architectural_style":"Vernacular, with a shape reminiscent of Greek Revival but no ornament","criteria":[],"status_note":"Described as in fair condition inside and outside, with a dilapidated appearance; used for warehouse storage.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.642886-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/79003928.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71984930","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/erie-county/old-vermilion-mill-79003928/"}
