The image displays the interior of a large, brightly lit indoor swimming complex, identified as likely the National Sports Academy "Vassil Levski" swimming pool in Sofia, Bulgaria. The facility contains a multi-lane competitive swimming pool, with at least eight lanes delineated by multicolored ropes featuring blue, red, green, and white segments. The pool water is clear blue, exhibiting reflections from the overhead lighting and windows. At the far end of the pool, a series of numbered starting blocks are positioned. Alongside these blocks, to the right, blue stacked benches or chairs are present, and a distant, partially obscured figure is seated. One male swimmer, wearing a dark swim cap and goggles, is visible in the water in the second lane from the right, with his upper torso exposed above the water. The pool deck consists of dark gray, textured non-slip tiles, with drainage grates running along the pool's edge. In the immediate foreground, dark blue tiled stairs with a dark metallic handrail descend to the pool deck level. The walls are light-colored, featuring blue trim and pillars. Large, tall, multi-paned windows dominate the upper section of the far wall, providing ambient natural light. On the left wall, two flags are mounted vertically: the national flag of Bulgaria (green, white, red vertical stripes) and the flag of the European Union (blue field with 12 gold stars). The ceiling is light-colored and reflective, equipped with numerous recessed rectangular light fixtures. A yellow net, resembling a water polo goal, is partially visible in the background near the windows, and a large digital scoreboard or display is visible on the far right wall.
