It includes early 19th century houses, an 1901 grist mill, a dam, a metal truss bridge and archeological sites.","why_significant":"The grouped houses, mill, dam, bridge and archeological sites illustrate the scale and relationships of a rural, family milling enterprise in early 19th century Monroe County, an area built largely on flour milling. They show the sequential development of the site begun by settler-miller Joseph Sibley. Well-documented archeological sites also provide a basis for further study of ceramic types in western New York.","narrative":"Along Big Black Creek in southwestern Monroe County, this fifty-acre district preserves the working landscape of a small family milling operation. Its core includes two frame houses from 1825 and 1835, a board and batten barn, an ice house, a mill dam, a metal truss bridge carrying Stuart Road, and a one-story frame grist mill built in 1901 after earlier mills burned. Across the road stands the Sibley-Stuart House, a cobblestone dwelling of about 1835 with a Federal doorway and oval gable window. The area is tied to Joseph Sibley, an early settler and miller who later held several public offices, and to later owners who rebuilt and operated the mills until 1925. A flooded flow site west of Route 33A is included because of its connection to the mill's history. Excavations by the Rochester Museum and Science Center uncovered a log cabin, a saw mill and a cooper shop, with artifacts dated 1825 to 1865. Together these remains document the sequence of milling development.","period_of_significance":null,"architect_builder":null,"architectural_style":"Greek Revival (early frame house); cobblestone construction with Federal doorway (Sibley-Stuart House)","criteria":[],"status_note":"The form states the 1901 grist mill and two frame houses were being restored by their owners; the district is occupied, with private residences.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:39.155212-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/75001198.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75318778","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/monroe-county/chili-mills-conservation-area-75001198/"}
