It also notes the building's association with John D. Rockefeller, Sr., who closed the 1847 Weddell House inn to make room for it, and its ownership history involving the Rockefeller family and Josiah Kirby.","narrative":"Rising sixteen stories at 614 Superior Avenue in Cleveland, this office building was constructed between 1903 and 1910 of masonry and metal to designs by the firm Knox and Elliot. It measures roughly 200 by 150 feet, with the north side divided into two shafts that form a light court. The first three floors on the south and east sides carry an ornamental cast iron facade with Sullivanesque foliage, an arch over the south entrance and a denticular cornice. Upper floors have paired double-hung windows between masonry piers. John D. Rockefeller, Sr. acquired the site, closed the 1847 Weddell House inn despite public protest, and commissioned the new building at a cost of about $1 million. It was later sold to his son, passed to Josiah Kirby in 1920 and renamed the Kirby Building, then was bought back by Rockefeller in 1923 and renamed. The building remains in good condition and in constant use.","period_of_significance":"1903-1910","architect_builder":"Knox and Elliot","architectural_style":"Commercial","criteria":[],"status_note":"Described as in good condition and in constant use; ground-floor shops are still occupied and the interior has been little altered.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:09.109431-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/73001416.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/73001416/6fd92ed8df-800.webp","url_1600":"https://nationalhistoricalregister.com/media/73001416/6fd92ed8df-1600.webp","licence":"CC BY-SA 2.0","author":"Doug Kerr from Albany, NY, United States","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Rockefeller_Bldg.jpg\" rel=\"noopener\">Doug Kerr from Albany, NY, United States</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Rockefeller_Bldg.jpg"},"district":{"nrhp_refnum":"82003558","name":"Cleveland Warehouse District","url":"https://nationalhistoricalregister.com/districts/ohio/cleveland-warehouse-district-82003558/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71987375","wikipedia":"https://en.wikipedia.org/wiki/Rockefeller_Building_(Cleveland)","wikidata":"https://www.wikidata.org/wiki/Q21016130"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/cuyahoga-county/rockefeller-building-73001416/"}
