It was built around 1838-9 as a double blacksmith shop.","why_significant":"The nomination argues it is a distinguished, intact example of mid-nineteenth century commercial masonry in Lyme, with some of the finest stonework in the town, including dressed limestone lintel courses and quoins. It is also tied to the Wilcox shipyard, which drove the growth of Three Mile Bay in the late 1830s and 1840s.","narrative":"Built around 1838-9 on Main Street in Three Mile Bay, this one and one-half story limestone building began as a double blacksmith shop. Its walls are coursed quarry-dressed limestone, with smooth-dressed stone used for trim, a lintel course and corner quoins. The shop was started by Asa Wilcox and the young blacksmith Aura Wilson to supply metal ship parts to the Wilcox shipyard, and it held two forges, one for the yard and one for the community. Its masonry is described as some of the finest in the town of Lyme, and similar details appear on the nearby Charles Wilcox farmhouse, suggesting a common master mason. After the railroad ended the shipbuilding era in the early 1850s, the building kept working as a blacksmith shop into the twentieth century. It later became an automobile repair shop in the 1920s and a boat repair shop in the 1960s. Despite replaced doors and some replaced windows, it keeps much of its original appearance and two-room plan.","period_of_significance":null,"architect_builder":"Architect and builder unknown","architectural_style":null,"criteria":["C"],"status_note":"Condition rated good; used for storage and as boat engine repair space and office, with a boat supply and repair business using the building.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:45.257388-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/90001328.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75313190","wikipedia":"https://en.wikipedia.org/wiki/Old_Stone_Shop","wikidata":"https://www.wikidata.org/wiki/Q7085123"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/jefferson-county/stone-shop-old-90001328/"}
