This massive structure that sits in the middle of the city is the stadium. It is surrounded by the civilization that supports it. The inhabitants of the city are not visible in this photo, but they do exist.

The tall buildings closest to it look to be like hotels or condominiums. They could be non-dwellings too. The colorful buildings near the top of the photo are a community where people live. You can even see traffic on the road leading to that community. Many of the buildings of the city climb up a hill and are not built on a flat plain.
