It opened as the Ohio Center on September 10, 1980, and although sometimes considered a white elephant because of its small size and seating capacity (concert fans usually found themselves driving to Cincinnati Riverfront Coliseum, Indianapolis Market Square Arena, Detroit Joe Louis Arena, Cleveland Richfield Coliseum or Pittsburgh Mellon Arena), it has been used for a variety of events, including concerts (Conway Twitty, Devo, Elvis Costello & The Attractions, The Stray Cats, Rick Springfield, Kiss (2/19/84), Culture Club, Ratt, The Pointer Sisters, Cyndi Lauper, Billy Idol, Billy Ocean, Richard Marx, Queensrÿche), trade shows, and sporting events such as the 1993 and 1994 Mid-American Conference men's basketball tournaments. The exhibit hall was also the home of professional wrestling cards from the early 1980s to mid-1990s with monthly visits from the WWF and the occasional WCW event. The hall totals 90,000 square feet (8,400 m2) of exhibit space - 65,000 on the main floor and 25,000 on the balcony, and can be divisible into two halls. The first entertainment event at the facility was comedian Rodney Dangerfield and special guest McGuffey Lane on September 20, 1980 attended by 6,677 persons.

Columbus Union Station was an intercity train station in Downtown Columbus, Ohio, near The Short North neighborhood. The station and its predecessors served railroad passengers in Columbus from 1851 until April 28, 1977. The first station building was the first union station in the world, built in 1851. Its replacement was built from 1873 to 1875, just before demolition of the first station building. After traffic problems on High Street, as well as increased rail traffic became problematic, a new station was planned by Daniel Burnham beginning in 1893. The new station opened in 1897, and its arcade along High Street was finished in 1899. By 1928, part of the arcade was demolished. Passenger service significantly declined from the 1950s to the 1970s. The arcade was demolished in 1976 to make way for a new convention center, although it had been placed on the National Register of Historic Places two years prior. Train service stopped at Union Station in 1977, and the remaining portions of the station were demolished in 1979. The demolished arcade was delisted in 1999. A portion of the arcade was saved, the Union Station arch, which is the focal point of the McFerson Commons park in the nearby Arena District.
