The house is said to remain virtually unchanged, with no modern alterations, and the surrounding land preserves the feel of an early country estate.","narrative":"Graeme Park is a two-and-a-half story house of brown fieldstone with a high gambrel roof, roughly 60 by 25 feet, with walls two feet thick. William Keith, Provincial Governor of Pennsylvania, built it in 1721-22 as a malt house on an estate first called Fountain Low. In 1739-40 Dr. Thomas Graeme converted it into a summer residence and installed paneling of high Georgian quality. The large first-floor drawing room has a fully paneled wall, a Greek fret cornice, and a fireplace with a broken pediment overmantel, while the second-floor parlor has delft tile around its fireplace. The exterior is largely unornamented, which the nomination contrasts with the interiors. Ownership passed through the Graeme family and later to Samuel Penrose, and the Commonwealth of Pennsylvania received the property in 1958. The house is significant for its interiors and for the early estate setting it retains.","period_of_significance":"1721-1740","architect_builder":null,"architectural_style":"Georgian","criteria":["C"],"status_note":"Restored by the state and operated as a state park; the nomination notes archaeological investigation and restoration underway.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:31.089707-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/66000672_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/66000672/0d67b385a5-800.webp","url_1600":"https://nationalhistoricalregister.com/media/66000672/0d67b385a5-1600.webp","licence":"CC BY 3.0","author":"en:User:MikeParker (Michael H.
