The Cleveland Convention Center was a convention center located in downtown Cleveland, Ohio, in the United States. Built by the city of Cleveland beneath the Cleveland Mall adjacent to Public Auditorium, it was completed in 1964. Plans for the convention center were first made in 1956, but voters twice rejected initiatives to fund construction before approving a bond levy in November 1963. A local private foundation donated several million dollars to beautify the mall atop the convention center with a reflecting pool and fountains.
