The image displays a large, unfinished, concrete-lined underground shaft or tunnel under construction in the Capital City of Prague, Czechia. The structure presents a significant upward slope leading towards an external opening. Its interior walls are composed of rough, textured concrete with patches of lighter and darker gray. A central, wide ramp, covered in dark, wet, granular material, likely a mix of excavated earth and concrete residue, traverses the incline. Along the right wall, a wooden staircase with dark metal handrails ascends, paralleled by a dark utility pipe secured to the wall. A crumpled blue object, resembling fabric or a tarp, lies on the lower left portion of the central ramp. Through the distant opening, an active exterior construction site is visible, featuring exposed steel structural beams, scaffolding, and partially constructed building components. Multiple construction workers, distinguished by orange high-visibility clothing and hard hats, are present in the background area, engaged in work-related activities; one individual appears to be operating a piece of equipment on the ground.
