It was designed and built in 1872 by John Blythe.","why_significant":"The house is significant for architecture as the work of John Blythe, a local builder and architect who introduced the Italianate style to the area and shaped the town's post-Civil War appearance. It is considered the most elegant and best-preserved of his houses, and it is a key example of the ell-plan house type he used for high-style residences.","narrative":"Built in 1872 by the local builder and architect John Blythe, this two-story, five-bay brick house on West Main Street in Monongahela City shows the Italianate style in its ell plan, paired wooden brackets, and segmentally arched windows with wooden cornice moldings and oversized keystones. It was made for David Longwell, a riverboat captain and engineer, who contracted for the new house after railroad tracks were laid a few feet from his earlier home at the river end of the lot. Blythe designed many Italianate buildings in the town between 1864 and 1889, and this house is regarded as the most elegant and best preserved of his residences. It is one of nine ell-plan houses documented as his designs, and it keeps a steep metal bay roof, a round portal window in the gable, and a winding center-hall staircase that the others lack. The house faces Chess Park, and its porch was removed in later years. Its listing rests on its architecture and its link to Blythe's work.","period_of_significance":"1872","architect_builder":"John Blythe (architect/builder)","architectural_style":"Italianate","criteria":["C"],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:36.747429-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/93000718.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/93000718/2603bc93ab-800.webp","url_1600":"https://nationalhistoricalregister.com/media/93000718/2603bc93ab-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:David_Longwell_House.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:David_Longwell_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996586","wikipedia":"https://en.wikipedia.org/wiki/David_Longwell_House","wikidata":"https://www.wikidata.org/wiki/Q5236756"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/longwell-david-house-93000718/"}
