The image shows a small square window in a white wall. The window is rectangular in shape and appears to be made of concrete or stucco. The frame of the window is made of a light-colored material, possibly stone or concrete, and it is slightly raised from the wall. Through the window, we can see a greenish-blue mesh-like pattern on the surface. The mesh is slightly uneven and has a rough texture. The overall appearance of the wall is weathered and aged.
