The Congress hall of the G2A Arena is the largest space of its kind in the whole region. It is equipped with the best audio, lighting, and stage equipment.

There are 872 seats and a stage with electrically controlled platforms (for a choir for example). Above the stage, a screen has been installed that is 10 meters wide and 6 meters high. The screen is meant to work with the highest class projector capable of projecting images in HD.

Above the hall, in the mezzanine, there are 12 interpreting rooms which make it possible to organize multinational events with participants from all over the world. Besides that, on the mezzanine, there is also a spot from which all the equipment in the hall can be managed.

The Congress Hall has direct access to the professional technical room and backstage for performers that consists of makeup room, dressing room, and bathroom. Beside the main entrances on the ground and first floors, the congress room is also accessible from outside the facility, making it easier to organize events regardless of what is happening in the rest of the facility.

The interior was covered with veneered panels of natural wood, which allows for the best acoustics.

Oak parquet guarantees the best quality and makes the vast and splendorous hall also comfortable for visitors.
