The image displays the ruins of a large stone structure in Vrela, Montenegro, under an overcast sky. The primary subject is a partially destroyed circular stone tower or bastion, constructed from grey, rectangular cut stone blocks. Its uppermost section is incomplete, and a significant vertical breach on the left side exposes internal rubble. Several narrow, rectangular openings are visible in the lower portion of the circular wall. Leaning against the circular structure is a two-bar metal frame, possibly a rudimentary ladder or support, with two horizontal crossbars, resting on scattered rocks at its base. To the left of the circular ruin, a longer, straight section of the ruined stone wall extends, featuring multiple arched openings. In front of this straight wall, a white and yellow multi-panel signpost is anchored in the ground. The immediate foreground consists of sparse green grass and dry, brown brush. Behind the ruins, several bare deciduous trees are visible. The background features distant hills or mountains partially obscured by low-lying clouds or mist. No individuals are present in the scene.
