It includes a stuccoed masonry mansion and carriage house built c.1864, plus a cottage (c.1890), a carpenter's shop (c.1900) and dairy barns (1916).","why_significant":"The nomination argues the estate is the most significant example of its type, period and method of construction in the Hudson Highlands. It also notes the property's association with Samuel Sloan, a prominent railroad executive and one of the locality's more significant individuals. The estate is said to retain integrity of design, setting, materials, workmanship and location.","narrative":"Oulagisket is a large Italianate estate on the east side of Route 9D near Garrison, overlooking the Hudson River. Railroad executive Samuel Sloan built the two and one-half story stuccoed masonry mansion around 1864, with a three-story hipped-roof tower, arched windows with keystones, block brackets and arcaded chimneys. Nearby stand a stuccoed carriage house, a superintendent's cottage from about 1890, a carpenter's shop from about 1900 and a dairy barn and stable complex from 1916. Sloan, born in Northern Ireland in 1817, led the Hudson River Railroad and later the Delaware, Lackawanna and Western. After his death the estate passed to Vassar College, which found it too costly to maintain and arranged to sell the outbuildings in the early 1950s. The estate is recognized for its architectural distinction, its intact wooded setting and its link to a leading local figure. The buildings are now residences.","period_of_significance":null,"architect_builder":null,"architectural_style":"Italianate","criteria":[],"status_note":"Condition is given as good; the buildings are now used as residences.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:42.590761-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/82001253.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75314412","wikipedia":"https://en.wikipedia.org/wiki/Oulagisket","wikidata":"https://www.wikidata.org/wiki/Q7110435"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/putnam-county/oulagisket-82001253/"}
