It was the headquarters of the East Ohio Gas Company and included the first attached parking garage in downtown Cleveland. Its cast-in-place concrete superstructure was completed in six months, a record for the city at that time.","narrative":"Rising 21 stories above East 9th Street in downtown Cleveland, this office tower was built for the East Ohio Gas Company and occupied in 1959. New York firm Emery Roth and Sons designed it in the International Style for Tishman Realty and Construction. The exterior combines black granite at street level with an aluminum and glass curtain wall above, and a concrete structural grid shows through the facade. An attached garage of about 522 spaces was the first of its kind downtown. Builders used cast-in-place reinforced concrete and finished the superstructure in six months, a local record. The most important interiors are on the first floor: the main lobby, the East Ohio Gas Payment Center with its teller stations and travertine floor, and the Gas Light Theater with its terrazzo reflecting pool, wood paneling and scalloped plaster ceiling. The building is recognized for its commercial history, architecture and engineering, and it is currently vacant.","period_of_significance":"1958-1963","architect_builder":"Emery Roth and Sons (architects); The Tishman Realty and Construction Group","architectural_style":"Modern Movement: International Style","criteria":["A","C"],"status_note":"The building is currently vacant; upper floors have been emptied and the first-floor commercial and gas payment spaces are vacated.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:07.0074-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/12001212.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/12001212/87c150c2a0-800.webp","url_1600":"https://nationalhistoricalregister.com/media/12001212/87c150c2a0-1600.webp","licence":"CC BY 2.0","author":"Ohio Office of Redevelopment","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:East_Ohio_Building.jpg\" rel=\"noopener\">Ohio Office of Redevelopment</a>, <a href=\"https://creativecommons.org/licenses/by/2.0\" rel=\"license noopener\">CC BY 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:East_Ohio_Building.jpg"},"district":{"nrhp_refnum":"02000702","name":"Euclid Avenue Historic District","url":"https://nationalhistoricalregister.com/districts/ohio/euclid-avenue-historic-district-02000702/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71987822","wikipedia":"https://en.wikipedia.org/wiki/1717_East_Ninth_Building","wikidata":"https://www.wikidata.org/wiki/Q4552487"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/cuyahoga-county/east-ohio-building-the-12001212/"}
