It was designed by local architects Clinton Vivian and Arthur Gibb for the Cascadilla School.","why_significant":"The nomination argues the building is significant as a surviving example of a second-phase American collegiate boathouse type, combining boat bays with social and later athletic space. Although the loss of its tower, veranda and wood roof means it is no longer a distinctive example of Shingle style, it keeps its plan, boat rooms and functional divisions. It also records rowing's shift from a social pastime to an athletic activity by 1899.","narrative":"Built between 1894 and 1896 on the south shore of Cayuga Lake, where Fall Creek enters the water, this T-shaped, wood-framed boathouse was designed by Ithaca architects Clinton Vivian and Arthur Gibb for the Cascadilla School. Originally it had conical towers, a wraparound second-story veranda and dark stained shingles. It held boat rooms, lockers and showers downstairs, with a large assembly room and committee room above for banquets, dances and receptions. By 1899 the upper floor was converted into a gymnasium and game rooms as rowing became more athletic than social. The city of Ithaca acquired the property in 1923, and school crews rowed from it until 1930. Later losses include the round tower, most of the veranda and the original shingle roof. The nomination nonetheless values the building as an intact example of an early boathouse type, since its boat rooms, plan and many interior finishes remain. A local rowing club now uses it.","period_of_significance":null,"architect_builder":"Clinton Vivian and Arthur Gibb","architectural_style":"Shingle Style","criteria":[],"status_note":"Boat bays still in use by a rowing club; second-floor assembly room/gym used for city storage; former committee room is a caretaker's apartment; third-floor apartment is vacant but intact.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:44.923616-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/91001498.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/91001498/6136285d18-800.webp","url_1600":"https://nationalhistoricalregister.com/media/91001498/6136285d18-1600.webp","licence":"Public domain","author":"Rotograph Co.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Ithaca_-_Cascadilla_recreation_building.jpg\" rel=\"noopener\">Rotograph Co.</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Ithaca_-_Cascadilla_recreation_building.jpg"},"district":{"nrhp_refnum":"100008895","name":"Stewart Park","url":"https://nationalhistoricalregister.com/districts/new-york/stewart-park-100008895/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75322473","wikipedia":"https://en.wikipedia.org/wiki/Cascadilla_School_Boathouse","wikidata":"https://www.wikidata.org/wiki/Q5048218"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/tompkins-county/cascadilla-school-boathouse-91001498/"}
