Nicosia airport terminal. Situated in the no man’s land between the Greek and Turkish part of Cyprus.
I saw this very nice Reuters image set that inspired me to look up a higher resolution picture of the abandoned terminal. You can find more images of the airport and other parts of the Nicosia no man’s land here.
You cannot visit these places as it is a demilitarized zone. No matter how cool it would be to walk around there, it’s probably not worth getting shot for.
