Elevating a Cobb icon
The Cobb Galleria is now the
Cobb Convention Center
The newly renamed Cobb Convention Center Atlanta is Georgia's premier mid-size convention venue for tradeshows, meetings and special events. The Cobb-Marietta Coliseum & Exhibit Hall Authority, owner and operator of the Center, has assembled an enviable team of Cobb County-based firms to manage the design and construction of the expansion and renovation. This transformative project broke ground in fall of 2025 and will be completed in early 2027.
