It is a Georgian-plan house with a dressed stone front wall and rubble stone side and rear walls.","why_significant":"The nomination argues the house is a fine example of late eighteenth century rural Pennsylvania architecture and a record of rural stone building design and craftsmanship based on the traditional Georgian floor plan. It is described as having come down to the present practically unchanged, with its solid stone exterior and original interior woodwork, doors, hardware and stair intact.","narrative":"Built of stone in the late eighteenth century, the John Gray house stands in Port Matilda, Centre County, Pennsylvania. It is a two and one-half story, five-bay structure with an exposed basement, a dressed stone front wall, rubble stone side and rear walls, and a steep gable roof with a chimney at each end. The front and north walls are sheltered by a porch, and the nine-over-six windows have raised panel shutters on the first floor. A small one-story board and batten wing from the twentieth century projects from the rear. Inside, a center hall divides two rooms on each side, following the typical Georgian plan. The stair is distinctive for its sawn flat balusters and gouged ornament on the string facings. Most of the woodwork, doors, trim, chair rails, floors and hardware survive original, and the house was restored under the direction of a qualified restoration architect. Its listing rests on its value as a well-preserved example of rural eighteenth century stone architecture in Central Pennsylvania. The house was built by John Gray, one of the early settlers of the region.","period_of_significance":"1793","architect_builder":"John Gray (builder)","architectural_style":"Georgian","criteria":["C"],"status_note":"Restored under the direction of a qualified restoration architect; the document lists the condition as good.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:31.030032-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/75001628.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/75001628/42e5288d83-800.webp","url_1600":"https://nationalhistoricalregister.com/media/75001628/42e5288d83-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Gray_House_Centre_Co_PA_porches.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:Gray_House_Centre_Co_PA_porches.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997848","wikipedia":"https://en.wikipedia.org/wiki/John_Gray_House_(Port_Matilda,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q15229663"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/centre-county/gray-john-house-75001628/"}
