Omaha Civic Auditorium

Omaha Civic Auditorium is a multi-purpose convention center located in Omaha, Nebraska. Opened in 1954, it surpassed the Ak-Sar-Ben Coliseum as the largest convention/entertainment complex in the city, until the completion of CenturyLink Center Omaha in 2003. With the opening of the Ralston Arena in 2012, all teams that played at the Civic Auditorium moved, which reduced the venue's viability. Wikipedia*
