The village formed from the settlements of Sekitan (c. 1870) and East Addyston, incorporated together in 1891.","why_significant":"The district is a largely intact single-industry company village that grew around a pipe-manufacturing plant established in 1889. It preserves rows of workers' housing in eight vernacular house types built around 1890, along with churches, schools, commercial and social buildings. The form argues these house types are important vernacular architectural resources. The full Section 8 statement is not included in the supplied text.","narrative":"Addyston is a small industrial village stretched for about a mile along the Ohio River just west of Cincinnati. It grew from two hillside settlements, Sekitan and East Addyston, which were incorporated together in 1891, and it developed around a pipe-manufacturing plant established in 1889. The district takes in nearly all of the town's main streets and part of the plant, which is now operated by Monsanto. Of roughly 400 buildings, about 260 are houses, and most date from the village's first fifteen years. Eight recurring house types, mostly frame, gable-fronted and built around 1890, line the narrow streets in rows, including L-plan, T-plan, side-gable and pyramidal-roof forms. Six churches, two schools, a fire station, a social hall, boarding houses and commercial buildings are mixed in among them. Aluminum siding, replaced windows and small additions have altered some buildings, but the village still reads clearly as a company-driven workers' community.","period_of_significance":null,"architect_builder":null,"architectural_style":"Stick/Eastlake, Queen Anne, and vernacular workers' house types","criteria":[],"status_note":"Most of the village remains in residential, industrial, religious and commercial use.
