Southworth. It sits in the Prospect Avenue Historic District and is used as a fraternity house.","why_significant":"The nomination argues the house is a good representative example of Italianate residential architecture, with its bracketed cornice, eyelet windows and ornate stone hood molds. It is also one of the few remaining Post Civil War houses on Cleveland's near east side. It was the home of businessman William Southworth and of Louisa Southworth, who was active in the local woman suffrage movement.","narrative":"Built about 1879 at 3334 Prospect Avenue in Cleveland, this two-story brick house is an example of Italianate residential design. Its features include a cornice with paired brackets set between small eyelet windows, segmented-arch windows topped by stone hoods, and a double-door entrance. A Neo Classic front porch and a one-story enclosed side porch were added in 1895. A two-story Tudor Revival carriage house stands behind the house and is vacant and in poor condition. The house was built for W.P. Southworth, who owned a wholesale and retail grocery company and served as president of the National City Bank from 1879 to 1889. His wife, Louisa Southworth, was active in the local woman suffrage movement, wrote articles on the subject, and in 1893 led local efforts to gather signatures supporting women's right to vote. She lived there until her death in 1905. The house is one of few surviving Post Civil War residences on Cleveland's near east side.","period_of_significance":null,"architect_builder":null,"architectural_style":"Italianate","criteria":[],"status_note":"House in good exterior condition and used as a fraternity house; the rear Tudor Revival carriage house is vacant and in poor condition.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:15.060235-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/84000234.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/84000234/d06ab3b717-800.webp","url_1600":"https://nationalhistoricalregister.com/media/84000234/d06ab3b717-1600.webp","licence":"Public domain","author":"User:Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Southworth_House_closeup.jpg\" rel=\"noopener\">User:Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Southworth_House_closeup.jpg"},"district":{"nrhp_refnum":"100006160","name":"Midtown Historic District","url":"https://nationalhistoricalregister.com/districts/ohio/midtown-historic-district-100006160/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71984668","wikipedia":"https://en.wikipedia.org/wiki/Southworth_House_(Cleveland)","wikidata":"https://www.wikidata.org/wiki/Q2304810"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/cuyahoga-county/southworth-house-84000234/"}
