It was built in two sections, the original Federal barn dated 1792 and a larger later addition from the early to mid 19th century.","why_significant":"The nomination argues the barn is a significant historic structure in its own right and that listing protects the integrity of the Cressbrook Farm house and the historic scene. The original 1792 portion is described as possibly the only signed bank barn in Pennsylvania, bearing inscriptions of its builders and occupants. Both sections show fine stone and wood work.","narrative":"Built into a hillside at Valley Forge, this detached two-story stone and wood Pennsylvania bank barn has an upper threshing and mow floor entered by wagon doors at grade, with stables on the lower level facing a stone-walled barnyard. The original Federal section was completed in 1792 and bears a date stone and inscribed names of its builders, including Jonathan Moor, along with those of William and Mary Davis and John Harvard. A larger three-bay addition from around 1830 to 1850 doubled the barn's size and was entered over a covered wood bridge. Its massive hand-hewn, pegged timber framing and stone work are described as fine. The barn lies within 150 feet of the Duportail Farmhouse, the former quarters of Brigadier General Louis Lebègue Duportail during the 1777-78 encampment, and its significance is tied to protecting that house and the historic scene around it.","period_of_significance":"1792 and circa 1840","architect_builder":"Jonathan Moor","architectural_style":"Pennsylvania bank barn","criteria":[],"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 17:11:33.185434-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003469.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003469/c20c1defa4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003469/c20c1defa4-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Federal_Barn.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Federal_Barn.JPG"},"district":{"nrhp_refnum":"66000657","name":"Valley Forge National Historical Park","url":"https://nationalhistoricalregister.com/districts/pennsylvania/valley-forge-national-historical-park-66000657/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998460","wikipedia":"https://en.wikipedia.org/wiki/Federal_Barn","wikidata":"https://www.wikidata.org/wiki/Q5440024"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/federal-barn-80003469/"}
