Metropolitan Cathedral of Athens in Municipality of Athens

You're standing on Mitropoleos Square, in front of the Metropolitan Cathedral of Athens. It's the cathedral of the Archbishop of Athens and all of Greece, and locals simply call it the Mitropoli. Its official dedication is to the Annunciation of the Mother of God. Take a look at those massive walls. They were built with marble taken from seventy-two demolished churches. So in a way, a whole lot of old Athenian churches live on in this one.
