Traveling the roads of Greece, it won’t be long until the metal boxes on skinny wire legs catch your attention. It may take a few of them blurring by before you realize what you’re seeing is not a bizarre mailbox or the Greek version of a roadside telephone. Behind the small glass doors, a candle flickers, a color picture of a saint stares back, and the top of the box is crowned with a cross or perhaps a row of Greek letters. Farther along, a brightly whitewashed building the size of a children’s playhouse stands out against the grey-green leaves of the olive trees.
