It is also an unusually well-preserved and finely detailed example of the last Queen Anne three-deckers built in the city.","narrative":"Built around 1906, this three-decker at 23 Endicott Street in Worcester belongs to a row of similar houses facing Crompton Park in the Island neighborhood, a working-class area south of downtown. Its first owner, James O'Connor, was a gasfitter who lived in the building, and early tenants included blacksmiths, woodworkers and a machinist. Many residents were Irish and Swedish, later joined by Polish and Lithuanian families, and worked in nearby factories close to the railroad junction. The house is a late example of the Queen Anne three-decker, with a side-hall plan, hip roof, clapboard siding and wide bands of wood shingle wrapping the front bay. An ornate three-tier porch has lathe-turned posts, cut brackets and spindle friezes, and bracketed window caps and cornice brackets add detail. It was listed for its link to the neighborhood's development and for its well-preserved design.","period_of_significance":null,"architect_builder":null,"architectural_style":"Queen Anne","criteria":["A","C"],"status_note":"Recorded as in fair condition, with no major alterations and still in residential use.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:04.317383-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/3/7934/63793403/content/electronic-records/rg-079/NPS_MA/89002419.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/89002419/fec34bf172-800.webp","url_1600":"https://nationalhistoricalregister.com/media/89002419/fec34bf172-1600.webp","licence":"CC BY-SA 3.0","author":"Pvmoutside","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:James_O%27Connor_3_Decker.jpg\" rel=\"noopener\">Pvmoutside</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:James_O%27Connor_3_Decker.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63793403","wikipedia":"https://en.wikipedia.org/wiki/James_O%27Connor_Three-Decker","wikidata":"https://www.wikidata.org/wiki/Q6140471"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/worcester-county/oconnor-james-three-decker-89002419/"}
