spiral staircase viewed from directly above

spiral staircase viewed from directly above. Numerous white cords or wires hang down from the ceiling, fanning out in a radial pattern. The staircase itself is constructed of metal with a circular railing and steps. The walls appear to be dark, possibly concrete or metal, with some reflective surfaces. There is an orange accent band visible on the staircase railing further down. The perspective creates a sense of depth and leads the eye towards the center of the spiral. The scene is devoid of any people or animals. The location is identified as the spiral staircase in the Stockholm City Hall, Sweden.
