The buildings were constructed around 1877 and are now used as Berwick City Hall and the Police Station respectively.","why_significant":"The nomination argues the complex is a significant example of American architectural design from the period when Italianate and Second Empire styles were at the peak of popularity, with the mansion's styles shown in largely unaltered form. It also ties the house to the industrial development of Berwick through the Jackson family, and describes the mansion as one of the most significant surviving Victorian-era structures in the city.","narrative":"Built around 1877 on a corner of the former Jackson & Woodin Manufacturing Company grounds in Berwick, the Jackson Mansion is a three-story house with a basement, hipped roof, and projecting towers topped by mansard roofs. Its walls are faced with imported Vermont stone, giving it a castle-like appearance, and its main entrance sits beneath a pedimented portico with Doric columns. A two-story Carriage House of the same stone stands to the rear, crowned by a central cupola. The house was designed by Brugler, an architect from Danville, and combines Second Empire and Italianate forms with Eastlake woodwork. It was built for Colonel Clarence Gearhart Jackson, a Civil War veteran and Republican leader who was vice-president of the Jackson & Woodin Manufacturing Company. The surviving interior, with its carved staircase, plaster ceilings and paneling, reflects the wealth of the family and the late nineteenth-century taste for eclectic design.","period_of_significance":"1877","architect_builder":"Mr. Brugler (architect)","architectural_style":"Second Empire and Italianate, with Eastlake woodwork details and eclectic combination of styles","criteria":[],"status_note":"Presently used as Berwick City Hall (mansion) and Police Station (carriage house); interior altered during conversion to public offices.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:34.114969-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/85001965.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85001965/b64780aa7f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85001965/b64780aa7f-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Jackson_Mansion_Berwick_PA.jpg\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Jackson_Mansion_Berwick_PA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994634","wikipedia":"https://en.wikipedia.org/wiki/Jackson_Mansion_and_Carriage_House","wikidata":"https://www.wikidata.org/wiki/Q6117235"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/columbia-county/jackson-mansion-and-carriage-house-85001965/"}
