It absorbs the earlier North Main Street Historic District and extends east and south of it.","why_significant":"The district is argued to preserve the entire historic core of the city, with civic, religious, residential and commercial buildings that keep their architectural integrity. It shows a wide range of nineteenth and early twentieth century American styles. Areas beyond the boundary were left out because of modern intrusions and heavy alteration.","narrative":"Canandaigua's historic core is protected as a district of 354 properties, 338 of which contribute to its character. Buildings date from the 1810s to the 1930s and are made of brick, wood and stone. Atwater Park, a landscaped green on North Main Street, is the focal point, surrounded by civic and religious landmarks such as the Ontario County Courthouse, the post office, City Hall and the First Congregational Church. North of the park, North Main Street holds the largest and most elaborate houses, while Howell and Gibson Streets feature Queen Anne, Italianate and Federal mansions. South of the park lies the commercial center of two- and three-story masonry blocks, mostly from the third quarter of the nineteenth century, and nearby working-class streets with modest frame homes. The district expands an earlier North Main Street district to cover the whole historic center. Its boundaries exclude areas where modern construction and heavy alterations weaken the historic setting.","period_of_significance":null,"architect_builder":null,"architectural_style":"Wide range of styles including Federal, Greek Revival, Gothic Revival, Italianate, Italian Villa, Queen Anne, Eastlake, Colonial Revival, Neoclassical and Art Moderne","criteria":[],"status_note":"354 properties, of which 338 contribute and 16 are non-contributing; the area remains a mix of residential, commercial, religious and civic uses.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:48.418951-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/84002856.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/16000345/eef387918c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/16000345/eef387918c-1600.webp","licence":"CC BY-SA 3.0","author":"Daniel Case","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Historic_building_row_on_Main_Street,_Canandaigua,_NY.jpg\" rel=\"noopener\">Daniel Case</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Historic_building_row_on_Main_Street,_Canandaigua,_NY.jpg"},"district":{"nrhp_refnum":"84002856","name":"Canandaigua Historic District","url":"https://nationalhistoricalregister.com/districts/new-york/canandaigua-historic-district-84002856/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75314103","wikipedia":"https://en.wikipedia.org/wiki/Canandaigua_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q5031115"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/ontario-county/canandaigua-historic-district-boundary-increase-16000345/"}
