Anyone taking a walk in the historic district of Athens (known as Plaka) will certainly have walked past this wall, seen it, maybe even photographed it. It is the Northern side of the Acropolis wall.
But saturated with too much to see in too short a time, people scarcely ever notice what they see. Or, perhaps, we’re just not very perceptive as a species. The truth is that every single time I ask people to tell me if they’ve noticed anything odd about this wall, I draw blank stares or plain negatives.
And yet -to me- it is plainly obvious that this wall is unlike any other.
Am I wrong? Please, take a look and tell me if you notice anything unusual about it.
I promise to explain the mystery after I get a few of your opinions first.
