An upward-angled view captures an indoor event space located in Dortmund, Germany

An upward-angled view captures an indoor event space located in Dortmund, Germany. A large, square-shaped lighting truss system, constructed from silver-colored aluminum scaffolding, is suspended from a white grid-patterned drop ceiling. The truss supports multiple black stage lighting fixtures, including several parabolic-shaped spotlights, various rectangular LED wash lights, and at least two square LED matrix lights featuring circular lenses. Electrical cabling is routed along the truss structure. The white modular ceiling incorporates recessed circular lights, linear fluorescent light panels, and multiple circular ventilation grilles with a distinctive starburst design. A single red circular fire alarm sensor is centrally visible on the ceiling. The surrounding walls are smooth and white. On the right side of the image, a tall section of vertical windows with light-colored wooden frames allows natural light into the space. The scene is devoid of people or discernible activity.
