The image displays a sunlit architectural passage within the Jiayuguan Fort complex in Jiayuguan, China, leading into an open courtyard. The passage is defined by two high, parallel walls of light brown, weathered bricks. On the left, a thick, cylindrical red pillar is partially visible, supporting an overhead structure. The ceiling of the passage features horizontal reddish-brown wooden beams, above which a richly decorated wooden frieze with blue, green, orange, and gold patterns is present. The floor is paved with light grey bricks laid in a herringbone pattern. A dark conduit with a small rectangular electrical box is affixed to the lower section of the right passage wall. Beyond the passage, the courtyard is brightly illuminated by direct sunlight, casting a sharp shadow across the front section of the passage floor. Within the courtyard, a building with light-colored walls and multiple steps leading to an entrance is visible on the right, topped with similarly decorated beams. To the left, a low, slatted wooden fence and additional aged brick walls are discernible. No individuals or dynamic actions are depicted.
