Most structures were built between 1860 and 1920.","why_significant":"The nomination argues the district represents the peak of Williamsport's social, economic and cultural history, built during the prosperous lumber era. Its concentration of elaborate mansions reflects the wealth of the lumber barons who built them. Architect Eber Culver and builder Peter Herdic are credited with many of the most imposing Second Empire homes, and the district contains a wide range of Victorian styles.","narrative":"Most of the buildings in this residential district in central Williamsport are Victorian-era houses, built mainly between 1860 and 1920 during the city's lumber boom. The district holds 289 buildings, of which 102 are classed as significant. Williamsport's growth came after the 1847 establishment of a log boom on the Susquehanna River, which drew sawmills, railroads and timber wealth to the city. Lumber figures rose sharply, from 196,953 logs in 1862 to 1,816,562 in 1891. Eber Culver designed many of the larger homes, and builder Peter Herdic constructed several of them, including an 1855 Italianate house at 407 West Fourth Street. The district's houses range from Second Empire mansions to Queen Anne, Eastlake and Romanesque examples. The area was subdivided into apartments after the 1936 flood and the 1940s growth of a nearby technical institute.","period_of_significance":"1855-1920","architect_builder":"Eber Culver (architect); Peter Herdic (builder)","architectural_style":"Victorian (Second Empire, Queen Anne, Eastlake, Italianate, Victorian Gothic, Romanesque, Colonial Revival, Neo-Classical)","criteria":["A","C"],"status_note":"The district is described as deteriorating in general condition, with many large houses subdivided into multi-family rental units.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.739432-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/85000120.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85000120/47c3b5b1f2-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85000120/47c3b5b1f2-1600.webp","licence":"CC BY-SA 4.0","author":"Beyond My Ken","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Millionaire%27s_Row_Hermance_House_Williamsport.jpg\" rel=\"noopener\">Beyond My Ken</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Millionaire%27s_Row_Hermance_House_Williamsport.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998766","wikipedia":"https://en.wikipedia.org/wiki/Millionaire%27s_Row_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q15253418"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lycoming-county/millionaires-row-historic-district-85000120/"}
