It is also cited as a rare surviving high style Federal example in Schuylkill County with a high degree of integrity, and as one of the oldest surviving homes in the city.","narrative":"Built about 1830 on a knoll set back from Mahantongo Street in Pottsville, this two-and-one-half story brick mansion is a high style Federal town house with a side hall and double parlor plan. Its exterior has changed little since construction, with Flemish bond facade brickwork, six-over-six sash, a semicircular lunette over the front door, and a standing seam metal roof. Burd Patterson, who moved to Pottsville in 1826, proved in 1835 that anthracite could be mined below the water table using the slope method. In 1840 his Pioneer Furnace produced anthracite pig iron for three months, winning a five thousand dollar prize offered by Philadelphia bankers. The house is regarded as a rare surviving example of its style in Schuylkill County, and the Queen Anne porch and Victorian alterations are also valued as part of its architectural history.","period_of_significance":"C. 1830-1900","architect_builder":null,"architectural_style":"Federal","criteria":["B","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 17:11:36.185864-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/95000515.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/95000515/8501cde398-800.webp","url_1600":"https://nationalhistoricalregister.com/media/95000515/8501cde398-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:BURD_PATTERSON_HOUSE.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ MD</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:BURD_PATTERSON_HOUSE.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997876","wikipedia":"https://en.wikipedia.org/wiki/Burd_Patterson_House","wikidata":"https://www.wikidata.org/wiki/Q4998246"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/schuylkill-county/patterson-burd-house-95000515/"}
