If you walk over one block to Metropolis Street which runs from Syntagma Square parallel to Ermou there is this small church and a block down the main cathedral of Athens.
But the cathedral was damaged by an earthquake around 30 years ago and has been under scaffolding ever since. It is kind of an embarrassment for the church, or it should be.
If it can be fixed then fix it. If you have to tear it down and build another one then do it.
But to leave it with scaffolding on it for 30 years while you try to decide what to do is not the way to win converts to the faith.
