Its center section was erected in 1793, and brick wings of four bays were added in 1816.","why_significant":"The building is presented as a fine example of a post-Colonial vernacular style in Western Pennsylvania, combining Georgian, Roman Classical and Adamesque forms in local builders' own way. It is described as a unique variation of Western Pennsylvania stone building and among the most interesting architectural remains in the district. It also served as the administration building of the Washington Academy for seventy-six years before becoming the administration building of the college in 1869.","narrative":"Built in 1793 as the administration building of the Washington Academy in Canonsburg, this three-bay, two-story stone building has a center entrance and a two-story pedimented portico on four Tuscan columns. Its random rubble facade has squared quoins that suggest regular stone courses, and its 12-over-12 sashes are original to construction. Brick four-bay wings were added in 1816. The portico reflects Jeffersonian architecture from Virginia, adapted to Western Pennsylvania. After the Washington Academy merged with Jefferson College in 1865, the trustees voted in 1869 to locate the combined college at the Washington site, and this building became the administration building of Washington and Jefferson College. It is regarded as a distinctive regional example of early stone construction in the area and remains in good use today.","period_of_significance":"1793-1816","architect_builder":null,"architectural_style":"Roman Neo-Classic, Jeffersonian interpretation of the Palladian scheme; late Georgian masonry, Post Colonial style","criteria":[],"status_note":"Well maintained and in excellent condition because of continued use","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.553981-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/77001199.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/77001199/35434e8929-800.webp","url_1600":"https://nationalhistoricalregister.com/media/77001199/35434e8929-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:McMillan_Hall_western_front.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:McMillan_Hall_western_front.jpg"},"district":{"nrhp_refnum":"100005206","name":"Washington Commercial Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/washington-commercial-historic-district-100005206/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994899","wikipedia":"https://en.wikipedia.org/wiki/McMillan_Hall","wikidata":"https://www.wikidata.org/wiki/Q6802362"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/administration-building-washington-and-jefferson-college-77001199/"}
