Atlanta's Signature Event Center

Cobb Galleria Centre features state-of-the-art event space in one of Atlanta's most in-demand neighborhoods. Tirelessly dedicated to the details, we’ve amassed a national reputation for hosting top-tier events of all shapes and sizes.

Transformation Is On The Horizon

The Cobb-Marietta Coliseum & Exhibit Hall Authority, owner and operator of Cobb Galleria Centre, Georgia’s premier mid-size convention venue for tradeshows, meetings and special events, has assembled an enviable team of Cobb County-based firms to manage the design and construction of the expansion and renovation of Cobb Galleria Centre. This transformative project is scheduled to break ground in fall of 2025 and be completed in early 2027.
