It was the summer retreat of railroad and canal magnate Samuel Decker Coykendall, tied to wilderness tourism and the fly-fishing history of the nearby Beaverkill. Its use of local limestone also relates it to the Ulster County stone house tradition.","narrative":"Coykendall Lodge is a large, rambling summer lodge built in 1899 beside Alder Lake in the Upper Beaverkill Valley, in Hardenbergh, Ulster County. It rises two and one-half stories on a base of rough-hewn Ulster County limestone, with a stone porch, a porte-cochere, cedar shingle upper floors and steeply pitched gables. The grounds cover about 1610 acres and include a low stone wall with cairns and the remains of a trout hatchery. Samuel Decker Coykendall, who led the Ulster & Delaware Railroad and helped open the Catskills to tourists, built it as a retreat for fishing, hunting and entertaining. Its design draws on the Great Camps of the Adirondacks and on the region's historic stone houses, and it is linked to the fly-fishing heritage of the Beaverkill. Later used as a Boy Scout lodge, it has stood vacant for nearly twenty years, leaving many interior finishes damaged, though the central hall keeps its coffered ceiling and stone fireplace.","period_of_significance":"1899","architect_builder":null,"architectural_style":"Late 19th & Early 20th Century American Movements/Craftsman; Late Victorian/Shingle Style (description also notes Stick Style influence)","criteria":["C"],"status_note":"Current function listed as vacant/not in use; the interior has deteriorated after almost twenty years of vacancy, though the main block layout remains essentially as built.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:53.185951-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/01001441.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75322584","wikipedia":"https://en.wikipedia.org/wiki/Coykendall_Lodge","wikidata":"https://www.wikidata.org/wiki/Q5180014"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/ulster-county/coykendall-lodge-01001441/"}
