Allstate Arena

The Allstate Arena is an arena in Rosemont, Illinois, which is home to the Chicago Wolves hockey club, DePaul University men's basketball, Chicago Sky (WNBA) basketball organization and was the home of the defunct Chicago Rush Arena football team. It is located near the intersection of Mannheim Road and Interstate 90, adjacent to O'Hare International Airport.

History
The facility, originally named the Rosemont Horizon, was intended to be the home of the WHA Chicago Cougars, but the franchise folded in 1975. The Village of Rosemont issued $19 million in bonds to finance the cost of the arena with exclusive contracts with Araserv, the Ringling Bros. and Barnum & Bailey Circus, and MFG International.

On August 13, 1979, the uncompleted roof of the Rosemont Horizon collapsed, killing five construction workers and injuring 16 others.

In 1999, the Allstate Insurance Company paid $20 million to renovate it and gain its naming rights. That same year, it hosted the Great Midwest Conference men’s basketball tournament. The building hosted the National Collegiate Athletic Association basketball tournament three times: the 1987 and 1993 Midwest Regional first and second round games, and the 2005 Chicago Regional Finals.
