The Irwin M. Krohn Conservatory is a conservatory located in Eden Park within Cincinnati, Ohio in the United States.HistoryThe conservatory was completed in 1933, replacing smaller greenhouses that had stood in Eden Park since 1894. Originally known only as the Eden Park Greenhouse, in 1937 it was renamed in honor of Irwin M. Krohn, who served as Board of Park Commissioner from 1912 to 1948. The architect firm Rapp & Meacham designed the conservatory in the Art Deco style, in the form of a Gothic arch.A 1966 hailstorm caused extensive damage to the conservatory, and the firm of Lord & Burnham was called to restore it. The original wooden sashes were replaced with durable aluminum.
