It holds a row of three-story gable-roofed brick commercial buildings on State Street and a group of brick commercial/industrial buildings on Mill Street, all built between 1844 and 1868.","why_significant":"The district is argued to be significant for its link to commercial and industrial growth on Rochester's west side, when the city was a mill center and Erie Canal boom town. It is also valued as a locally rare and well-preserved set of mid-nineteenth-century commercial and industrial buildings. The State Street row is the oldest surviving building group from the early development of the Frankfort neighborhood.","narrative":"This one-acre block on the northwest edge of downtown Rochester, New York, combines two building groups from the mid-nineteenth century. Along State Street runs the Teoronto/Smith Block, a row of three-story, five-bay brick buildings under continuous gable roofs, with stone sills and lintels and apartments above storefronts. A limestone plaque reads \"Teoronto Hall\" and \"Smiths Block.\" Around the corner on Mill Street stand brick industrial buildings from the 1850s and 1860s, with brick cornices, flat roofs, cast iron columns and wood mill framing. The block was built between 1844 and 1868, when Rochester was growing as a mill center and Erie Canal boom town. It is the oldest surviving building group from the early Frankfort neighborhood and connects State Street with the nearby Brown's Race industrial area. Storefronts and rear areas have been heavily altered, and several upper floors are badly deteriorated, but the building shells have changed little since the nineteenth century.","period_of_significance":"1844-1883","architect_builder":null,"architectural_style":"Greek Revival","criteria":["A","C"],"status_note":"Current function is listed as vacant/not in use; the State Street storefronts have been replaced with plywood and the upper floors of several buildings are severely deteriorated, while the Mill Street building at 281 is used for plumbing supply storage and offices.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:48.50433-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/10000798.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/10000798/a010a67b26-800.webp","url_1600":"https://nationalhistoricalregister.com/media/10000798/a010a67b26-1600.webp","licence":"CC BY-SA 3.0","author":"MohawkPhotographer","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Teoronto_Block_Historic_District_2013-09-28_14-17-18.jpg\" rel=\"noopener\">MohawkPhotographer</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:Teoronto_Block_Historic_District_2013-09-28_14-17-18.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75318954","wikipedia":"https://en.wikipedia.org/wiki/Teoronto_Block_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q7701192"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/monroe-county/teoronto-block-historic-district-10000798/"}
