Collinsville Soccer Complex, also known as The Fields was a planned soccer-centered development to be located in Collinsville, Illinois, United States. The centerpiece of the complex was an 18,500-seat soccer-specific stadium that would have been the home stadium for professional soccer clubs in MLS and WPS based in the St. Louis area. The plan also included eight FIFA-approved artificial turf fields, as well as mixed-use development, which included retail, office, entertainment, educational, and residential areas. The entire development was valued at almost $600 million.
