It contains 62 counted resources, mostly masonry commercial buildings of one to five stories, plus one church, an industrial complex, and two bridges.","why_significant":"The district is significant under Criteria A and C. It reflects the city's commercial and industrial development tied to the oil industry, and it holds a cohesive collection of commercial buildings from the 1890s through the 1940s that represent many popular architectural styles. Some buildings are documented as the work of local and regional architects.","narrative":"Oil City's downtown commercial core lies on both banks of Oil Creek just north of its meeting with the Allegheny River. The district's buildings are mostly brick, stone and terra cotta blocks of one to five stories, set flush to the sidewalk in a dense street grid. Construction runs from the 1890s through the 1940s, after a combined flood and fire in June 1892 destroyed much of the earlier downtown. The architecture reflects the popular styles of those decades, including Italianate, Romanesque Revival, Chateauesque, Colonial Revival, Neo-Classical Revival and Art Deco. The district's significance rests on its links to the oil industry, which turned Oil City into a regional hub for refining and pipelines. Its commercial blocks, banks, offices and the Boiler Works complex document how that industry shaped the city's economy, and its buildings preserve a notable range of regional architecture.","period_of_significance":"ca. 1870-1945","architect_builder":"Emmett E.
