Walls of 250 gabions have been created around the stage, in which approximately 2,000 tons of Latvian boulders have been used. Behind the stage there are changing rooms, next to which there are two exhibition, trade and event areas covered with clinker bricks and granite pavement. The stage is complemented by a roof, which improves the acoustics and prolongs the event season. The roof visually resembles a shell, it has a unique large-sized bent glued wood construction. The longest total span in this structure is 60 meters, but in total about 530 cubic meters of wood are used in the construction of the stage roof. It is the only roof of its kind in the Baltics, and the only one in the world in this solution and performance. During the event, the roof is able to protect 700 spectators in the seats and 500 spectators on the ground floor from the sun's rays and adverse weather conditions.
