It holds five extant Harmony Mills buildings and the adjoining Harmony Hill (Prospect Hill) neighborhood of factory housing.","why_significant":"The surviving text describes the district as a mill complex with an associated company neighborhood of brick and wood workers' housing, a tavern, a church, a school and the mill manager's mansion. The Section 8 statement of significance is not included in the excerpt, so the specific reasons for listing are not stated in the available text.","narrative":"Harmony Mill Historic District occupies a narrow shelf of land on the edge of an embankment above Cohoes Falls and the Mohawk River in Cohoes, New York. Five surviving mills form two rows parallel to the river. West and slightly south of them, a large neighborhood of brick and wood factory housing climbs the hill, known as Prospect Hill and Harmony Hill, where the street grid bends to fit the slope. The earliest housing is three blocks of two-and-one-half-story brick houses along Harmony Street, some with Greek Revival entrance trim. More plain brick and frame housing followed on Summit Street by 1866. The neighborhood also includes an old tavern, a church, a school and Johnston Hall, a rambling three-story brick Italianate mansion with a mansard roof, built for mill manager D.J. Johnston on a bluff overlooking the mills. The district extends north to include the Falls and was previously documented in a 1969 survey of the Mohawk-Hudson area.","period_of_significance":null,"architect_builder":null,"architectural_style":"Greek Revival trim on some of the earliest housing; Italianate for Johnston Hall (brick, three stories, mansard roof, hooded dormers)","criteria":[],"status_note":"Condition is marked good and altered, with both occupied and unoccupied status checked; present use includes commercial and industrial.
