This image depicts a section of an ancient Roman fortress wall located in the city of Hisarya, Bulgaria. The wall is constructed with a combination of stones, pebbles, and brickwork, indicative of Roman construction techniques. A notable feature is a semi-circular archway, likely an entrance or window, now appearing as a dark opening within the wall. The wall is heavily textured and weathered, with visible signs of age and wear. Patches of green vegetation, possibly grass or moss, are present along the base and top of the wall, suggesting the presence of moisture and organic growth. The background is dark, indicating the photograph was taken at night or in low-light conditions.
