The image displays a frontal view from inside a dim, brick-lined arched passage looking out towards a brightly illuminated exterior. This passage is located within the Mole Vanvitelliana (Lazzaretto) in the city of Ancona, Italy, opening towards the internal harbor basin. The immediate foreground and tunnel interior feature a barrel-vaulted ceiling and walls constructed from reddish-brown bricks, casting deep shadows. The floor is paved with dark rectangular blocks, embedded with approximately nine scattered square, reflective inlays. Four horizontal, dark strips, possibly a ramp or shallow steps, are visible on the floor in the closest foreground. Two rectangular, unlit light fixtures are mounted on the side walls of the passage, equidistant from the central opening. The passage terminates at a lighter, more open area defined by three arches crafted from yellowish-tan stone blocks. The central arch, prominent and brightly lit, frames the distant exterior. Two narrower, darker arched recesses are positioned symmetrically to its left and right. Two small, rectangular red signs bearing white text are affixed to the inner faces of the pillars supporting the central arch. Beyond the central arch, a body of light-blue water is visible, reflecting sunlight. A dark-colored boat is partially visible on the water. In the far background, a large, dark wooden arched gate spans over the water, integrated into a white or light-colored building structure. The sky above the distant structure appears bright and clear. No individuals are present in the scene.
