It is also known as Franklin Castle.","why_significant":"It is described as the most noted and one of the most architecturally distinguished residences on Franklin Avenue, the West Side counterpart of Euclid Avenue. It was designed by Cudell and Richardson, probably Cleveland's most important architectural firm of the 1880s, and few residences are positively attributed to them. It also reflects the newly rich merchant class of Cleveland's greatest period of industrial growth.","narrative":"Built in 1881 on Franklin Boulevard in Cleveland, this sandstone mansion was designed by the firm Cudell and Richardson for Hannes Tiedemann, a wholesale grocer and later a founder and vice president of a trust company. The Queen Anne house sits on a narrow 50-foot lot, with a tall street facade, a cylindrical tower with a conical roof, a mansard roof with stone dormers, and an ogee gable reminiscent of the Flemish style. Inside are twenty-six rooms, five fireplaces and a fourth-floor ballroom. Franklin Avenue was the West Side's equivalent of Euclid Avenue, and this house is considered its most noted residence. Cudell and Richardson designed major churches and progressive commercial buildings in the 1880s, though few houses are firmly attributed to them. The Tiedemann family lived here from 1866 to 1895. Later a German singing society and a social club occupied it, and it became widely known as Franklin Castle through publicity about its supposed haunting.","period_of_significance":"1800-1899","architect_builder":"Cudell and Richardson","architectural_style":"Queen Anne","criteria":[],"status_note":"Listed as occupied and in good condition, with a use as a private residence and museum; the form notes the house has been altered.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.163839-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/82004417.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82004417/e88c735c43-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82004417/e88c735c43-1600.webp","licence":"CC BY-SA 1.0","author":"Christopher Busta-Peck (Talk)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hannes_Tiedemann_House_Cleveland_Ohio.jpg\" rel=\"noopener\">Christopher Busta-Peck (Talk)</a>, <a href=\"https://creativecommons.org/licenses/by-sa/1.0\" rel=\"license noopener\">CC BY-SA 1.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Hannes_Tiedemann_House_Cleveland_Ohio.jpg"},"district":{"nrhp_refnum":"89000430","name":"Franklin Boulevard Historic District","url":"https://nationalhistoricalregister.com/districts/ohio/franklin-boulevard-historic-district-89000430/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71987552","wikipedia":"https://en.wikipedia.org/wiki/Franklin_Castle","wikidata":"https://www.wikidata.org/wiki/Q5491349"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/cuyahoga-county/tiedemann-hannes-house-82004417/"}
