The Chicago World Trade Center was a proposed 2500 feet (762 m) supertall skyscraper in Chicago, United States. It would have had 210 floors and it was also to look like the World Trade Center in New York that was destroyed on September 11, 2001. The building was designed in 1982 by Harry Weese for Stanley Raskow, Sr. However, the design was never built.
A shorter, 181 floor, 2,300-foot (700 m) building by the same name was proposed that same year, but like the other proposal, it was also cancelled.
In the absence of a physical structure, the World Trade Center Chicago became a seth organization organized as a not-for-profit in the State of Illinois, with a mission to promote international trade as part of the World Trade Center Association network of global offices of World Trade Centers.
In 2008, the World Trade Center Chicago was renamed the World Trade Center Illinois and moved from the Merchandise Mart to the Chicagoland Chamber of Commerce in the 80-floor Aon Center where tenants space was built to house international trade offices for lease. From 2006 to 2008, the World Trade Center and Chicagoland Chamber of Commerce held a close partnership to host international visitors and foreign delegations from around the world, primarily focusing on export promotion and business matchmaking for high level government and business leaders developing trade and investment relationships with Chicago-based businesses.
