The building shows Gothic influences in its stonework and lancet windows. It is also part of the Calvary Church complex, built from 1868 to 1925, in the proposed Clifton Avenue Historic District.","narrative":"Behind Calvary Episcopal Church on Clifton Avenue in Cincinnati sits a low, one-and-a-half-story Sunday school built in 1887 to designs by Samuel Hannaford & Sons. Built on the side of a hill, it is T-shaped, with steep intersecting slate gable roofs and random ashlar limestone walls. The taller center gable has a stone Gothic pattern around three narrow lancet windows, and the eastern gable end has unusually shaped stained glass windows with smooth limestone surrounds. A narrow vestibule links it to the church. The congregation was founded in 1846, and the main church was built between 1866 and 1868 to designs by William Tinsley. Sunday school attendance rose from 45 to 100 pupils between 1885 and 1887, and a large addition was dedicated in 1925. The building is listed as one of several works by the Hannaford firm, and it remains in use as a Sunday school in excellent condition.","period_of_significance":null,"architect_builder":"Samuel Hannaford & Sons (architect); builder unknown","architectural_style":"Gothic influences","criteria":[],"status_note":"Inventory lists interior and exterior condition as excellent; still used as a Sunday school.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.031986-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/80003040.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003040/a75ca6026c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003040/a75ca6026c-1600.webp","licence":"CC BY 3.0","author":"Photo by Greg Hume (Greg5030)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:CalvaryEpiscopal.jpg\" rel=\"noopener\">Photo by Greg Hume (Greg5030)</a>, <a href=\"https://creativecommons.org/licenses/by/3.0\" rel=\"license noopener\">CC BY 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:CalvaryEpiscopal.jpg"},"district":{"nrhp_refnum":"78002074","name":"Clifton Avenue Historic District","url":"https://nationalhistoricalregister.com/districts/ohio/clifton-avenue-historic-district-78002074/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71985346","wikipedia":"https://en.wikipedia.org/wiki/Calvary_Episcopal_Church_(Cincinnati)","wikidata":"https://www.wikidata.org/wiki/Q5024177"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/hamilton-county/calvary-episcopal-church-sunday-school-80003040/"}
