The nominated area includes the Mansion, the Avenue, the Boxwood Gardens, the Post Office and the Smokehouse.","why_significant":"The nomination argues the house is one of very few Georgian countryseats in Pennsylvania with a fully developed five-part plan, and that its Federal-period interiors, including six mantels with composition ornament attributed to Robert Wellford, are an unusually intact group. It also argues the 1895 remodelling is outstanding in its own right and that the garden plan, dated to 1800-1805, is a rare, largely intact example of a documented American formal garden predating 1840.","narrative":"Built in 1800-1805 of local cut red sandstone for Henry Bates Grubb, the five-bay Mansion at Mount Hope, near Manheim in Lancaster County, was designed as a formal Georgian countryseat with a fully developed five-part plan. Its Federal interiors survive in part, including the circular staircase, gouge-carved woodwork and several mantels with composition ornament attributed to Robert Wellford of Philadelphia. The house was extensively enlarged in 1895 with a ballroom, billiard room, dining room and conservatory, creating an eclectic exterior that combines Second Empire, Francis I and Colonial Revival features. The grounds include an avenue entered through sandstone gateposts, a terraced boxwood garden whose layout dates to the original construction, and stone outbuildings. The property is significant for its architecture, its formal garden and its link to the Grubb family's nineteenth-century iron industry, which was centred on the nearby charcoal furnace.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":"Federal; late Victorian additions of 1895 including Second Empire, Francis I and Colonial Revival elements","criteria":["A","B","C","D"],"status_note":"Listed property with the 1895 remodelling and later alterations noted; springhouse roof is in deteriorated condition and some windows are missing through neglect.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.263038-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003530.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003530/cb51bb5719-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003530/cb51bb5719-1600.webp","licence":"CC BY 2.0","author":"Mark from Baltimore, USA","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Mount_Hope_Estate2.jpg\" rel=\"noopener\">Mark from Baltimore, USA</a>, <a href=\"https://creativecommons.org/licenses/by/2.0\" rel=\"license noopener\">CC BY 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Mount_Hope_Estate2.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993295","wikipedia":"https://en.wikipedia.org/wiki/Mount_Hope_Estate","wikidata":"https://www.wikidata.org/wiki/Q6921302"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/mount-hope-estate-80003530/"}
