An exterior daytime photograph captures the Porte des Allemands (Germans' Gate) in Metz, France, beneath an overcast, gray sky. The central subject is a medieval fortified bridge-castle constructed from light-brown stone blocks, exhibiting varying degrees of weathering and patches of green moss. A dark, calm river flows through a large, low-lying arched passage at the base of the structure. Above the archway, the substantial stone wall of the bridge features numerous small, dark, rectangular openings and, on the right side, two larger rectangular windows with red frames. Two distinct white, circular, geometric art installations are affixed to the upper section of the stone wall: a spoked wheel design on the right and a multi-point star or rosette design on the left. In the background, two round stone towers with dark, conical roofs and weather vanes rise above the main wall, connected by a narrow, elevated passage. A segment of a square, crenellated stone tower is visible on the far left. Faint, light-colored cables are present in the sky behind the left tower. Green vegetation, including bushes and low-lying plants, covers the riverbanks and adheres to portions of the stone structure. No individuals or active vehicles are visible within the scene.
