The Colorado Convention Center (CCC) is a multi-purpose convention center located in Downtown Denver, Colorado. At 2,200,000 square feet it is currently the 12th largest convention center in the United States. Opening in 1990, the convention center expanded in 2004 to include several meeting rooms, two ballrooms and an indoor amphitheater. Since opening, the center hosts an average of around 400 events per year. Centrally located in the city, it has become one of Denver's many landmarks due to its architecture and is adjacent to the Denver Performing Arts Complex and is just blocks away from the Colorado State Capitol, Auraria Campus and the 16th Street Mall. The CCC is directly served via light rail by RTD's Theatre District–Convention Center station.
