The architect is unknown.","why_significant":"The nomination argues the house is a unique local example of Second Empire architecture that remains essentially unaltered, with fine stonework. It is also tied to Horace A. Lothrop, Sharon's leading industrialist of the mid-nineteenth century. Two stone-lined chambers beneath the front lawn are believed to have supplied gas for lighting and heating.","narrative":"Built in 1864 at 188 Ames Street in Sharon, Massachusetts, Stoneholm is a two-and-one-half-story Second Empire house of locally quarried, rock-faced granite ashlar. It has a slate mansard roof laid in a hexagonal pattern, a cupola, bracketed wooden porches and darker granite quoins and window trim. A granite carriage house with its own mansard roof stands on the 2.73-acre property, which is bordered by trees. The house was built for Horace A. Lothrop (1828-1898), who came to Sharon in 1847 and helped run a cutlery factory that kept its workers employed through business downturns. He later co-founded a shoe-shank firm, founded the Niantic Hose Company, served in the state legislature and on the school board, and gave to the public library, street lighting and shade trees. The nomination calls the house a unique local example of its style, remaining largely unaltered. Two stone-lined chambers under the front lawn are believed to have produced gas for lighting and heating.","period_of_significance":"1800-1899","architect_builder":"Architect Unknown","architectural_style":"Second Empire","criteria":[],"status_note":"Described as unaltered and in good condition, on its original site, and occupied; the carriage house has only minor alterations such as asphalt shingles replacing slates.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:54.313677-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/60/7963/63796360/content/electronic-records/rg-079/NPS_MA/80000648.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80000648/7a259898bd-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80000648/7a259898bd-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:SharonMA_Stoneholm.jpg\" rel=\"noopener\">User:Magicpiano</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:SharonMA_Stoneholm.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63796360","wikipedia":"https://en.wikipedia.org/wiki/Stoneholm","wikidata":"https://www.wikidata.org/wiki/Q7619230"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/norfolk-county/stoneholm-80000648/"}
