The image displays a segment of an underground tunnel identified as part of the Znojmo Underground in Znojmo, Czechia. The tunnel possesses an arched ceiling and walls constructed from rough, light-colored stone or concrete, exhibiting visible texture and signs of dampness. An alternating red and white plastic chain spans horizontally across the tunnel in the mid-ground, functioning as a physical barrier. The chain presents a slight sag in its center. The tunnel floor consists of an uneven, packed earth surface. A thin, dark cable is routed along the lower section of the left wall. Artificial light emanates from a source positioned deeper within the tunnel, illuminating the distant section and casting a forward glow. No individuals, actions, or interactions are visible within the scene.
