The image shows a narrow, concrete tunnel with a skylight in the center. The tunnel appears to be made of concrete and has a rough, uneven surface. The skylights are made of metal bars and are arranged in a way that creates a tunnel-like shape. Through the tunnel, we can see a view of trees and greenery outside. The sky is visible through the tunnel and the sunlight is shining through the trees, creating a bright and airy atmosphere. The overall mood of the image is peaceful and serene.
