Landmarks Event- Europe #41 Till Jan 21 - Piazza San Pietro (Saint Peter's Square)

There is not much to say about this, apart from that I was supposed to post this by 7 December, and instead it is going up on the morning of the 22nd. I am really sorry. Work just exploded, I still haven't bought a single Christmas present, and I am still working (until tonight), and I haven't solved any puzzle on this board in weeks. I really am sorry.

That being said, I kind of like this little puzzle. It is a bit of a trifle, but it did need a fair amount of research to get right. I do hope that you like it. As per usual, the puzzle is interspersed with the education. You will learn a lot about the square in going through the puzzle, but I have tried to mix the learning with the puzzle so that hopefully you do not notice too much. Enjoy.

Note: Normally you collect the passcodes from the landmarks from this week to gain access to a train for this week, but because I am so late, that is no longer required.
