The Colorado Convention Center 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.
The CCC has approximately 2,200,000 square feet of total indoor space.
Exhibit space is around 584,000 square feet (pre-expansion).
It also includes about 100,000 square feet of meeting / breakout rooms and around 94,656 square feet of ballroom space (prior to its latest expansion).
Recent Expansion:
Between 2021 and late 2023, CCC underwent a rooftop “vertical” expansion (i.e. built on existing roof) adding: • An 80,000 sq ft column-free multifunction ballroom • 35,000 sq ft of new pre-function / concourse space • A 20,000 sq ft outdoor terrace with views of downtown and the Rocky Mountains.
The expansion integrates with the existing structure and does not expand the building footprint outward.
Upon completion, the new expansion adds roughly 150,000 sq ft of meeting space and 600,000 sq ft of exhibit capability
Modernity / Features:
The new ballroom is column-free and highly flexible (divisible into multiple configurations) to suit large sessions or numerous breakout rooms.
Enhanced systems (HVAC, lighting, technology infrastructure) were included to support contemporary standards for health, comfort, and event tech.
The outdoor terrace offers scenic views of Denver’s skyline and the Rocky Mountains, making it an attractive amenity for receptions and social gatherings.
Popularity / Impact:
The CCC hosts around 400 events per year
For 2025, bookings are expected to generate a combined economic impact near $672 million from CCC events alone (with nearly 277,451 attendees).
The CCC is well positioned within downtown Denver, within walking distance of 13,000+ hotel rooms, adding to its attractiveness for large event planners.
Accessibility is strong: the CCC is served by light rail (Theatre District / Convention Center Station) and is centrally located in Denver’s walkable downtown.
