It was erected about 1813-1814 as the residence of Henry Cassel.","why_significant":"The nomination argues that the house is a major surviving example of Federal-period domestic architecture in Lancaster County and is the most intact brick, three-story, five-bay facade Federal house there. Its interior woodwork, including a spiral staircase described as the largest of its form surviving in the region, derives from two published pattern books. It is also linked to early commerce and banking through Henry Cassel, to a boys' boarding school opened in 1840, and to Marietta's 19th-century ironmasters.","narrative":"Marietta's Linden House is a three-story brick mansion with an L-shaped plan, built about 1813-1814 for Henry Cassel, a coal and lumber merchant who helped develop the east end of town. Its five-bay facade is laid in Flemish bond with cut sandstone sills and lintels, and the interior retains original eight-panel doors, moldings, and eight fireplaces, several with Tuscan and Doric engaged columns. The central hall holds a broad spiral staircase, the largest example of its form surviving in the region, and the woodwork follows two published pattern books of 1810 and 1811. Cassel opened a bank here in December 1813, later chartered as the Marietta and Susquehanna Trading Company, the first bank in Lancaster County outside the city. The house was a boys' boarding school from 1840, and between 1850 and 1889 it housed several ironmasters during Marietta's period as a leading iron-producing center. Its architecture and its commercial and industrial associations are the basis for its historic importance.","period_of_significance":"c. 1795-1830","architect_builder":null,"architectural_style":"Federal","criteria":[],"status_note":"The present roof of the front block and the attic gable ends are reconstructions after a fire in the early 1970s, and the three dormers facing East Market Street are not original.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.662091-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/83002254.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/83002254/0fe469c9ed-800.webp","url_1600":"https://nationalhistoricalregister.com/media/83002254/0fe469c9ed-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Marietta_Linden_House_LanCo_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:Marietta_Linden_House_LanCo_PA.JPG"},"district":{"nrhp_refnum":"84003446","name":"Marietta Historic District (Boundary Increase)","url":"https://nationalhistoricalregister.com/districts/pennsylvania/marietta-historic-district-boundary-increase-84003446/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996384","wikipedia":"https://en.wikipedia.org/wiki/Linden_House_(Marietta,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q15242403"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/linden-house-83002254/"}
