The image shows a large concrete structure with a tunnel on the left side. The structure appears to be made of concrete and has a sloping roof. On the right side of the structure, there is a large number "3000" written in black capital letters. The number is written in a modern, sans-serif font and is slightly larger than the rest of the numbers. In the foreground, there are two large rocks, one on the ground and the other on the wall. The sky is overcast and there are trees in the background.
