This image depicts a section of a concrete wall in the city of Podostrog, Montenegro, featuring an active drainage outlet. Centered on the upper left, a dark, cylindrical drain with vertical metal grates is embedded within the concrete structure. Dark, opaque water actively flows from this drain, cascading downwards in a thick stream along the wall. The concrete surfaces exhibit various shades of gray and tan, with evidence of water staining, efflorescence, and darker discoloration below the drain. Lush, vibrant green moss heavily covers the concrete in areas directly below and to the right of the water flow, indicating a consistently damp environment. Strong diagonal shadows are cast across the upper right and lower right portions of the scene, suggesting illumination from an external light source. At the base of the wall, pooled water reflects light, and minor organic debris is visible. No people are present.
