The International Exposition Center, also known as the I-X Center, is a convention and exhibition hall located in Cleveland, Ohio, adjacent to Cleveland Hopkins International Airport. The 2,200,000-square-foot (200,000 m2) building includes over 1,000,000 square feet (93,000 m2) total square feet of exhibition and conference space, making it one of the largest meeting, convention, and exhibition centers in the United States. The diverse show schedule includes public events featuring one of the country's largest boat shows, Trade Show 200 events, banquets and meetings attracting over 2 million visitors each year.
Originally located within Brook Park, Ohio, the building and 90 acres (36 ha) of neighboring land became part of Cleveland in a 2001 land swap that sent most of the NASA Glenn Research Center to Brook Park. It was built in 1942 as a General Motors-operated factory and was used to build bombers during World War II as the Cleveland Bomber Plant. For a time, it built the wing assembly for the B-29 Superfortress, then the experimental XP-75.
