A nighttime scene in Sofia, Bulgaria, displays the National Art Gallery (former Royal Palace) on Knyaz Alexander I Square, illuminated by an elaborate light projection. The building's facade is covered with dynamic, geometric light patterns in blue, green, and purple hues, creating an illusion of depth and movement. A dark, conical evergreen tree is positioned centrally in front of the illuminated building. To the left, an ornate black street lamp with two globes stands. Faint outlines of temporary structures are discernible at the base of the building. The foreground is a dark, empty expanse, likely a plaza. The sky above is dark and overcast, with a faint blue light streak visible in the upper right quadrant. No individuals are visible.
