The image depicts the Salle des Pas Perdus (Hall of Lost Steps) within the Palais de Rumine, located in Lausanne, Switzerland. The scene is a grand, empty hall characterized by its ornate architecture. The high ceiling features a prominent, circular stained-glass dome at its center, segmented by leaded lines into a radial pattern. The dome's panels display colorful figurative and abstract designs in hues of green, red, brown, and blue. Surrounding the dome, the ceiling and upper walls are extensively decorated with intricate, light-colored stucco work, including classical pilasters, friezes, and bas-relief sculptures of allegorical figures. A large, multi-tiered crystal chandelier with numerous illuminated bulbs hangs directly from the center of the stained-glass dome. Below, three tall, arched windows with dark wooden frames are visible, allowing natural light to illuminate the space. Through these windows, green foliage from trees is visible, indicating an outdoor natural environment. Wall-mounted sconces are present between the windows and on other wall sections. The floor is composed of light-colored wooden parquet, currently clear of any furniture or individuals. No people or active subjects are present in the static scene.
