It is presented as testimony to the prosperity of the farmer-owner after the Civil War and as among the most interesting architectural remains in the county.","narrative":"Centerville's Harrison House began as a five-bay, two and one-half story farmhouse of the Post Colonial Greek Revival type common in Washington County, built around 1845. Later remodeling added a two-story bay window with a turret roof and a square four-story tower, along with segmented round arch windows, stone and brick quoins, skewbacks, keystones, and bracketed eaves. These features turned a plain farm house into a High Victorian Italianate villa, which is unusual in the county. The house sits high on a ridge above Route 40, and its tall chimneys and arched lintels create an irregular skyline. The nomination links the transformation to the prosperity of the farmer-owner after the Civil War. Its architectural design is regarded as the most interesting among the county's remaining buildings of this type, and the house retains much of its character, apart from some replaced window sashes.","period_of_significance":"ca. 1845 and 1870","architect_builder":null,"architectural_style":"Italianate (High Victorian Italianate villa), built on a Post Colonial Greek Revival house form","criteria":["C"],"status_note":"Excellent condition; some segmented arch sashes have been replaced by flat top sashes; original site","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.14755-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/74001807.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/74001807/9e387e748b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/74001807/9e387e748b-1600.webp","licence":"CC BY-SA 3.0","author":"Generic1139","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Harrison_House_(Centerville,_Pennsylvania)_Lot.jpg\" rel=\"noopener\">Generic1139</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:Harrison_House_(Centerville,_Pennsylvania)_Lot.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994931","wikipedia":"https://en.wikipedia.org/wiki/Harrison_House_(Centerville,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q5665683"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/harrison-house-74001807/"}
